2021-08-17Make child sequence a listMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Since the `slink` function assigns values to the `listcopy` variable and its children, this commit ensures that the sequence is a list to allow for the assignment. If the child-sequence is a tuple, that would lead to an exception.
2021-08-04Fix issues caught by pylintMuriithi Frederick Muriuki
* gn3/computations/slink.py: remove unused imports * gn3/db/traits.py: remove unnecessary `else` clauses * tests/unit/db/test_traits.py: add docstrings for functions
2021-07-29Add partial type annotations for slink moduleMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Add some type annotations for the `nearest` function. * Leave some comments regarding the issues experienced when trying to add some typing annotations to the function to help with future endeavours of the same.
2021-07-26Fix issues caught by pylintMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Fix a myriad of issues caught by pylint to ensure the code passes all tests.
2021-07-23Add data examples for `slink`. Implement function.Muriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Copy the function, mostly verbatim from genenetwork1. See: https://github.com/genenetwork/genenetwork1/blob/master/web/webqtl/heatmap/slink.py#L107-L138 * tests/unit/computations/test_slink.py: Add a test with some example data to test that the implementation gives the same results as that in genenetwork1
2021-07-23Iterate through all valid pairsMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Fix the iteration construct. Given two lists of member coordinates, such as [0, 1] and [3, 5], the initial code would iterate over the pairs [0, 3] and [1, 5]. This commit fixes the iteration constructs such that the new code iterates over the pairs [0, 3], [0, 5], [1, 3] and [1, 5].
2021-07-23Extract function to flatten list of listsMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Extract the `__flatten_list_of_lists` function since it is used in more than one place.
2021-07-23Fix issue caught in `nearest` while testing `slink`Muriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * While running tests for slink, to try and understand what it is doing in order to write the appropriate tests for it, an issue arose that pointed a blindspot in the former understanding of now `nearest` should work. This commit fixes the issue found in both the expected data, and the code.
2021-07-23New function (`slink`): return [] on exceptionMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Add minimum code to pass new test * tests/unit/computations/test_slink.py: new test Add test to ensure that the new `slink` function return an empty list in case and exception is raised. Add the new `slink` function with minimum amount of code needed to pass the test.
2021-07-23Add dummy module documentationMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Add initial dummy module documentation in form of a python docstring Update the names of what would be private methods/function to start with a double-underscore (__) so that they do not show up in the default python documentation.
2021-07-23Add docstring for `nearest' functionMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: add documentation for the `nearest` function in the `gn3.computations.slink` module in the form of a (hopefully correct) python docstring.
2021-07-22Get shortest distance from two lists/tuples of member coordinatesMuriithi Frederick Muriuki
* gn3/computations/slink.py: add code to ensure new test passes * tests/unit/computations/test_slink.py: new test This one is a little weird: from https://github.com/genenetwork/genenetwork1/blob/master/web/webqtl/heatmap/slink.py#L57-L63 It gets rid of the last coordinates in both the lists of the member coordinates, and uses the remaining coordinates to find the shortest members. For example, given the following member coordinates: - i=[0,1,2] and j=[5,7,9], it uses [0,1] and [5,7] - i=[3,6,1] and j=[7,13], it uses [3,6] and [7] to find the shortest distances. I (fredmanglis) am not sure why it does it this way, since I'd have expected it to use all the coordinates, however, since at this time we need to retain bug-compatibility with the older code, I have done it as it is done in the old code. I also add a statement to raise an exception in the case where i and j are not lists of integers, or integers
2021-07-22Extract common `is_list_or_tuple' functionMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Extract the common function `is_list_or_tuple' making it accessible to later parts of the code.
2021-07-22Test for shortest distance between members in a list and coordinateMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: add code to pass new test * tests/unit/computations/test_slink.py: new test Given a list of members in a group, and a coordinate for a member in the same group, find the distance of the closest member from the given coordinate in the group.
2021-07-22Check that given list and both coordinates, we get shortest distanceMuriithi Frederick Muriuki
* gn3/computations/slink.py: Add code to compute the distance given the coordinate of both members on the parent list/tuple * tests/unit/computations/test_slink.py: * Change the name of the tests to more closely correspond to the business requirement the test is checking for * Update the comments to indicate some more things that might need to be done in the future
2021-07-22Check that all distances are positive or zeroMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: check that all distances between the 'somethings' are all either zero or positive. * tests/unit/computations/test_slink.py: * Remove data with all distances positive or zero, since it would fail the test * Change the expected message to more closely correspond to the business logic
2021-07-22Check that distance from A to B is same as from B to AMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: check that the distance from child A to B is the same as distance from child B to A. If not, throw an exception. * tests/unit/computations/test_slink.py: * Change the name of the test to more closely correspond to the business logic being tested. * Update the data in a separate test such that it does not error out due to failing to fulfill the expectations of separate requirement. - pass tests - Rename test - Fix errors: distances same both directions
2021-07-22Check that child distance from itself is zeroMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Check that a child's distance from itself is zero. If not, throw an exception. The children lists are a list of distances of "something" from other "somethings". There is still some need to establish what those "somethings" are, so that the test names can reflect the ideas that are actually being tested for. * tests/unit/computations/test_slink.py: Change the name of the test so that it more closely corresponds to the business logic it is actually testing, and not the mechanics of testing the idea.
2021-07-22Check the child lengths are same as length of parentMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Check that the child lists/tuples are the same length as the parent list/tuple. If any of the children is not the same length as the parent, throw and exception.
2021-07-22Add docstringMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Add docstring to the function, useful for generating automated developer documentation. We also surround the guard functions with some notification comments, to mark possible future places where change might be done.
2021-07-22Check that list and its direct children are not emptyMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Add code to pass the test that the list/tuple passed to `nearest' and its direct children lists/tuples are not empty.
2021-07-22Implement check for lists or tuplesMuriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * Implement the code to pass the check that a list of lists is passed to the `nearest' function.
2021-07-21Extract tests from code in GN1Muriithi Frederick Muriuki
Issue: https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/clustering.gmi * gn3/computations/slink.py: Add dummy `nearest' function * tests/unit/computations/test_slink.py: Add some tests This commit adds tests to try and reproduce the working of the `nearest' function in: https://github.com/genenetwork/genenetwork1/blob/master/web/webqtl/heatmap/slink.py This commit might not yet have extracted all the expected behaviour of the `nearest' function, and therefore, there is a possibility of a later commit augmenting the work in this commit.
