2022-05-21Return generator object rather than tuplesFrederick Muriuki Muriithi
Return generator objects rather than pre-computed tuples to reduce the number of iterations needed to process the data, and thus improve the performance of the system somewhat.

2022-05-06Hook up pcorrs with target traits computationsFrederick Muriuki Muriithi

2022-03-08Remove unused function and its testsFrederick Muriuki Muriithi
2022-03-08Fix tests, and issues caught by testsFrederick Muriuki Muriithi
Fix some issues caught by tests due to changes introducing the hand-off of the partial correlations computations to an external process Fix some issues due to the changes that introduce context managers for database connections Update some tests to take the above two changes into consideration
2022-02-25Fix issue where 0's were treated as False for the primary trait inzsloan
correlations In the original version of the if statement* I believe it was interpreted as "if a_val and (b_val is not None)". This caused values of 0 for a_val (the primary trait's values) to be evaluated as False. I changed it to compare both a_val and b_val to None. This seems to have fixed the issue. * if (a_val and b_val is not None)
2022-02-24gn3: computations: Call Popen with context manager.Arun Isaac
Context managers should be preferred when allocating resources. * gn3/computations/wgcna.py (stream_cmd_output): Call Popen with context manager.
2022-02-24gn3: Explicitly specify UTF-8 to be the file encoding.Arun Isaac
When the encoding is not specified explicitly, the system default encoding is used. This is not recommended. * gn3/computations/ctl.py (call_ctl_script), gn3/computations/gemma.py (generate_pheno_txt_file), gn3/computations/parsers.py (parse_genofile), gn3/computations/partial_correlations.py (partial_correlations_fast), gn3/computations/rqtl.py (process_rqtl_output, process_perm_output), gn3/computations/wgcna.py (dump_wgcna_data, call_wgcna_script), gn3/fs_helpers.py (jsonfile_to_dict): Explicitly specify UTF-8 to be the file encoding. * tests/unit/computations/test_gemma.py (TestGemma.test_generate_pheno_txt_file), tests/unit/computations/test_wgcna.py (TestWgcna.test_create_json_file): Test for call to open with encoding='utf-8' argument.
2022-02-21Fix minor issues introduced while fixing linting errorsFrederick Muriuki Muriithi
2022-02-21Fix a myriad of linter issuesFrederick Muriuki Muriithi
* Use `with` in place of plain `open` * Use f-strings in place of `str.format()` * Remove string interpolation from queries - provide data as query parameters * other minor fixes
2022-02-21Test partial corrs API with mix of existing and non-existing control traitsFrederick Muriuki Muriithi
Test that the partial correlations endpoint handles a mix of existing and non-existing control traits gracefully and issues a warning to the user. Summary of changes: * gn3/computations/partial_correlations.py: Issue a warning for all non-existing control traits * gn3/db/partial_correlations.py: update queries - use `INNER JOIN` for tables instead of comma-separated list of tables * tests/integration/conftest.py: Add `db_conn` fixture to provide a database connection to the tests. This will probably be changed in the future to connect to a temporary database for tests. * tests/integration/test_partial_correlations.py: Add test to check for correct behaviour with a mix of existing and non-existing control traits
2022-02-19Test partial corrs endpoint with non-existing control traitsFrederick Muriuki Muriithi
Test that if the endpoint is queried and not a single one of the control traits exists in the database, then the endpoint will respond with a 404 (not-found) status code. Summary of changes: * gn3/computations/partial_correlations.py: Check whether any control trait is found. If none is found, return "not-found" message. * gn3/db/partial_correlations.py: Fix bug in Geno query. * tests/integration/test_partial_correlations.py: Add test for non-existing control traits. Rename function to make it clearer what it is testing for. Remove obsoleted comments.
2022-02-18Test partial correlations endpoint with non-existent primary traitsFrederick Muriuki Muriithi
Test that the partial correlations endpoint responds with an appropriate "not-found" message and the corresponding 404 status code in the case where a request is made and the primary trait requested for does not exist in the database. Summary of the changes in each file: * gn3/api/correlation.py: generalise the building of the response * gn3/computations/partial_correlations.py: return with a "not-found" if the primary trait does not exist in the database * gn3/db/partial_correlations.py: Fix a number of bugs that led to exceptions in the case that the primary trait did not exist * pytest.ini: register a `slow` pytest marker * tests/integration/test_partial_correlations.py: Add a new test to check for an appropriate 404 response in case of a primary trait that does not exist in the database.
2022-02-17Add property tests for `dictify_by_samples`Frederick Muriuki Muriithi
Add property tests using pytest and hypothesis to test that the expected properties hold for the `gn3.computations.partial_correlations.dictify_by_samples` function.
2022-02-08Merge iterations to remove unnecessary computationsFrederick Muriuki Muriithi
Do all the work in a single iteration to avoid unnecessary iterations that hamper performance.
2022-02-08Remove multiprocessing for stabilityFrederick Muriuki Muriithi
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.
2022-02-08Give sorting functions more descriptive namesFrederick Muriuki Muriithi
2022-02-08Use multiprocessing to speed up computationFrederick Muriuki Muriithi
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.
2022-02-08Remove unnecessary computationFrederick Muriuki Muriithi
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()`

2022-01-12Update return type. Remove duplicate import.Frederick Muriuki Muriithi
The function is a generator function, since it uses a `yield` statement, and thus returns a generator object, that contains a tuple object. This fixes that. We also remove a duplicate import.
2022-01-10Use the correct letter case for the keysFrederick Muriuki Muriithi
* Use the correct case for the keys inorder to retrieve the correct values.
2022-01-10Indicate that string is an f-stringFrederick Muriuki Muriithi
* 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.
2022-01-10Remove all pairs with 'None' as the valueFrederick Muriuki Muriithi
* Remove all key-value pairs whose value is None.
2022-01-10Replace unoptimised function with optimised oneFrederick Muriuki Muriithi
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.
2022-01-10Convert NaN to NoneFrederick Muriuki Muriithi
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.
2022-01-10Add optimised entry for partial correlationsFrederick Muriuki Muriithi
Issue: * Function `gn3.computations.partial_correlations_optimised.partial_correlations_entry` is a copy of the `gn3.computations.partial_correlation.partial_correlations_entry` function that is optimised for better performance. The optimised function is intended to replace the unoptimised one, but it is included in this commit for comparison purposes, and to maintain some historical context for doing it this way.
