2022-02-08Merge iterations to remove unnecessary computations...Do all the work in a single iteration to avoid unnecessary iterations that hamper performance. Frederick Muriuki Muriithi
2022-02-08Remove multiprocessing for stability...Web servers are long-running processes, and python is not very good at cleaning up after itself especially in forked processes - this leads to memory errors in the web-server after a while. This commit removes the use of multiprocessing to avoid such failures. Frederick Muriuki Muriithi
2022-02-08Give sorting functions more descriptive namesFrederick Muriuki Muriithi
2022-02-08Use multiprocessing to speed up computation...This commit refactors the code to make it possible to use multiprocessing to speed up the computation of the partial correlations. The major refactor is to move the `__compute_trait_info__` function to the top-level of the module, and provide to it all the other necessary context via the new args. Frederick Muriuki Muriithi
2022-02-08Remove unnecessary computation...In Python3 when slicing, seq[:min(some_val, len(seq))] == seq[:some_val] because Python3 will just return a copy of the entire sequence if `some_val` happens to be larger/greater than the length of the sequence. This commit removes the unnecessary call to `min()` Frederick Muriuki Muriithi
2022-01-10Use the correct letter case for the keys...* Use the correct case for the keys inorder to retrieve the correct values. Frederick Muriuki Muriithi
2022-01-10Indicate that string is an f-string...* The string had the f-string syntax to format the values to be inserted into the string, but was missing the 'f' before the opening quotes to signify to python that this was an f-string. This commit fixes that. Frederick Muriuki Muriithi
2022-01-10Remove all pairs with 'None' as the value...* Remove all key-value pairs whose value is None. Frederick Muriuki Muriithi
2022-01-10Replace unoptimised function with optimised one...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Replace unoptimised function with one optimised to give better performance. The optimisation done here is to fetch multiple items/traits from the database per query, rather than the original form, which fetched a single item/trait from the database per query. Frederick Muriuki Muriithi
2022-01-10Convert NaN to None...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi Comment: https://github.com/genenetwork/genenetwork3/pull/67#issuecomment-1000828159 * Convert NaN values to None to avoid possible bugs with the string replace method used before. Frederick Muriuki Muriithi
2022-01-10Rework database functions to fetch multiple items...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * In an attempt to optimise the performance of the partial correlations feature, this commit reworks some database access functions to fetch multiple items from the database, per query, unlike their original forms which would fetch a single item per query. This reduces queries to the database, and should hopefully improve the responsiveness of the partial correlations feature. Frederick Muriuki Muriithi
2021-12-24Fix typing errorsFrederick Muriuki Muriithi
2021-12-24Fix sorting...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Update the sorting algorithm, for literature and tissue correlations so that it sorts the results by the correlation value first then by the p-value next. Frederick Muriuki Muriithi
2021-12-24Return the correlation method used...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Return the correlation method used Frederick Muriuki Muriithi
2021-12-24Reduce the total amount of data to be output...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * There is a lot of data that is not necessary in the final result. This commit removes that data, retaining only data relevant for the display. Frederick Muriuki Muriithi
2021-12-24Add dataset type to the results...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * The dataset type is relevant for the display of the data, therefore, this commit presents the dataset type as part of the results. Frederick Muriuki Muriithi
2021-12-17Add "success" status to final computation results...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi Frederick Muriuki Muriithi
2021-12-14linting: Fix obvious linting issuesFrederick Muriuki Muriithi
2021-12-14mypy: ignore some imports and errors...* Ignore some missing library stubs * Ignore some typing errors * Fix obvious typing errors Frederick Muriuki Muriithi
2021-12-14TO REVERT: Add logging to see data frameFrederick Muriuki Muriithi
2021-12-14Remove any items with less than 3 samples...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * pingouin raises an exception whenever one attempts to use it to compute the partial correlation with data that has less than 3 samples. Frederick Muriuki Muriithi
2021-12-14Fix dataset: use target dataset not primary...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Use the target dataset to load the target traits, not the primary trait's dataset, since they might differ. Frederick Muriuki Muriithi
2021-12-13Provide missing function...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Import the missing function. Frederick Muriuki Muriithi
2021-12-13Fix the removal of controls for corresponding Nones in targets...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Fix the code, so that it removes all control values, whose corresponding target values are None, without throwing an error. Frederick Muriuki Muriithi
2021-12-13Return the primary and control traits in addition to results...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * In addition to the partial correlation results, this commit enables the return of the chosen primary trait and the selected control traits. This data is required for presentation on the results page. Frederick Muriuki Muriithi
2021-12-13Run partial correlations against chosen database...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Run the partial correlations against the database that the user selects, and not the one from which the primary trait is. This was a bug in the code. Frederick Muriuki Muriithi
2021-12-09Prevent error on no result. Fix indexing...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * If the dataset name is not found, don't cause an exception, instead, return the provided search name. * Use the correct inner object Frederick Muriuki Muriithi
2021-12-08Provide group from primary trait...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * From the collections page, the group is not present, so this commit retrieves the group value from the primary trait. Frederick Muriuki Muriithi
2021-11-29Fix linting errors...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi Frederick Muriuki Muriithi
2021-11-29Provide entry-point function for the partial correlations...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Provide the entry-point function to the partial correlation feature. This is the function that ochestrates the fetching of the data, and processing it for output by the API endpoint (to be implemented). Frederick Muriuki Muriithi
2021-11-23Fix a myriad of linting errors...* Fix linting errors like: - Unused variables - Undeclared variable errors (mostly caused by typos, and wrong names) - Missing documentation strings for functions etc. Frederick Muriuki Muriithi
2021-11-23Migrate `getPartialCorrelationsNormal`...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Migrate the `web.webqtl.correlation.PartialCorrDBPage.getPartialCorrelationsNormal` function in GN1. * Remove function obsoleted by newer implementation of the code Frederick Muriuki Muriithi
2021-11-19Avoid rounding: compare floats approximately...Notes: https://github.com/genenetwork/genenetwork3/pull/56#issuecomment-973798918 * As mentioned in the notes, rather than rounding to an arbitrary number of decimal places, it is a much better practice to use approximate comparisons of floats for the tests. Frederick Muriuki Muriithi
2021-11-18Fix some linting errors...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Fix some obvious linting errors and remove obsolete code Frederick Muriuki Muriithi
2021-11-18Replace code migrated from R with pingouin functions...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Replace the code that was in the process of being migrated from R in GeneNetwork1 with calls to pingouin functions that achieve the same thing. Since the functions in this case are computing correlations and partial correlations, rather than having home-rolled functions to do that, this commit makes use of the tried and tested pingouin functions. This avoids complicating our code with edge-case checks, and leverages the performance optimisations done in pingouin. Frederick Muriuki Muriithi
2021-11-15Fix bugs in recursive partial correlations...* gn3/computations/partial_correlations.py: Remove rounding. Fix computation of remaining covariates * tests/unit/computations/partial_correlations_test_data/pcor_rec_blackbox_test.txt: reduce the number of covariates to between one (1) and three (3) * tests/unit/computations/test_partial_correlations.py: fix some minor bugs It turns out that the computation complexity increases exponentially, with the number of covariates. Therefore, to get a somewhat sensible test time, while retaining a large-ish number of tests, this commit reduces the number of covariates to between 1 and 3. Frederick Muriuki Muriithi
2021-11-15Fix the columns in built data frame...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * When the z value is a Sequence of sequences of values, each of the internal sequences should form a column of its own, and not a row, as it was originally set up to do. Frederick Muriuki Muriithi
2021-11-09Implement remaining part of `partial_correlation_recursive` function...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: implement remaining portion of `partial_correlation_recursive` function. * tests/unit/computations/test_partial_correlations.py: add parsing for new data format and update tests Frederick Muriuki Muriithi
2021-11-09Fix bug: if three columns, ensure last is "z"...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Fix a bug, caught when the function is called in a recursive form, with the "z*" columns reducing for each cycle through the recursive form. As it was, the last cycle through the recursive form would end up with a DataFrame with the columns "x", "y", and "z0" rather than the columns "x", "y", "z". This commit handles that edge case to ensure that the column name is changed from "z0" to simply "z". Frederick Muriuki Muriithi
2021-11-04Partially implement `partial_correlation_recursive`...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: Implement one path for the `gn3.computations.partial_correlations.partial_correlation_recursive` function. * gn3/settings.py: Add a setting for how many decimal places to round to * tests/unit/computations/test_partial_correlations.py: Update test to take the number of decimal places into consideration Implement a single path (where the z value is a vector and not a matrix) for the `partial_correlation_recursive` function. Frederick Muriuki Muriithi
2021-11-04Implement `build_data_frame`...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: new function (`build_data_frame`) * tests/unit/computations/test_partial_correlations.py: Add tests for new function Add a new function to build a pandas DataFrame object from the provided values: - x: a vector of floats (represented with a tuple of floats) - y: a vector of floats (represented with a tuple of floats) - z: a vector OR matrix of floats (represented with a tuple of floats or a tuple of tuples of floats) Frederick Muriuki Muriithi
2021-11-04Create blackbox tests for some functions migrated from R...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: new stub functions (partial_correlation_matrix, partial_correlation_recursive) * tests/unit/computations/partial_correlations_test_data/pcor_mat_blackbox_test.csv: blackbox sample data and results for variance-covariance matrix method * tests/unit/computations/partial_correlations_test_data/pcor_rec_blackbox_test.csv: blackbox sample data and results for recursive method * tests/unit/computations/test_partial_correlations.py: Tests for new function Provide some blackbox testing sample data for checking the operation of the functions migrated from R. Frederick Muriuki Muriithi
2021-11-01Stub `determine_partials`...Issue: * Stub out `determine_partials` which is a migration of `web.webqtl.correlation.correlationFunction.determinePartialsByR` in GN1. The function in GN1 has R code from line 188 to line 344. This will need to be converted over to Python. This function will also need tests. Frederick Muriuki Muriithi
2021-11-01Implement `compute_partial_correlations_fast`...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Implement `compute_partial_correlations_fast` that is a partial migration of `web.webqtl.correlation.PartialCorrDBPage.getPartialCorrelationsFast` in GN1. This function will probably be reworked once the dependencies are fully migrated. It also needs tests to be added. Frederick Muriuki Muriithi
2021-11-01Retrieve indices of the selected samples...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: New function (good_dataset_samples_indexes). * tests/unit/computations/test_partial_correlations.py: Tests for new function (good_dataset_samples_indexes) Get the indices of the selected samples. This is a partial migration of the `web.webqtl.correlation.PartialCorrDBPage.getPartialCorrelationsFast` function in GN1. Frederick Muriuki Muriithi
2021-10-29Explicitly round the values...* Explicitly round the values to prevent issues with the type-checker Frederick Muriuki Muriithi
2021-10-29Specify ten (10) decimal places...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: specify 10 decimal places * tests/unit/computations/test_partial_correlations.py: update examples Slight differences in python implementations, possibly hardware and operating systems could cause the value of float (double) values to be different in the less significant parts of the decimal places. This commit limits the usable part of the decimals to the first 10 decimal places for now. Frederick Muriuki Muriithi
2021-10-29Fix linting and typing errors...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi Frederick Muriuki Muriithi
2021-10-29Complete `build_temporary_tissue_correlations_table`...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * gn3/computations/partial_correlations.py: Remove comments after updating usage of the function at call point * gn3/db/correlations.py: Complete the implementation of the `build_temporary_tissue_correlations_table` function Frederick Muriuki Muriithi
2021-10-29Complete implementation of `batch_computed_tissue_correlation`...Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi * Complete the implementation of the `batch_computed_tissue_correlation` function Frederick Muriuki Muriithi
