Issue:

* gn3/partial_correlations.py: Implement a mostly, bug-compatible
  `export_informative` function as part of migrating the partial correlations
  feature over to GN3 from GN1
* tests/unit/test_partial_correlations.py: Implement tests to ensure the code
  work in a similar manner as that one in GN1.

Subject: Move 'export_trait_data' to 'gn3.db.traits' module

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/db/traits.py: Move function `export_trait_data` here
* gn3/heatmaps.py: Remove function `export_trait_data`
* tests/unit/db/test_traits.py: Move function `export_trait_data` tests here
* tests/unit/test_heatmaps.py: Remove function `export_trait_data` here

  Function `export_trait_data` more closely corresponds to the traits and is
  used in more than just the `gn3.heatmaps` module. This commit moves the
  relevant code over to the `gn3.db.traits` module and also moves the tests to
  the corresponding tests modules.

Subject: Move `export_informative` function to `gn3.db.traits` module

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/db/traits.py: Move `export_informative` function here
* gn3/partial_correlations.py: Remove `export_informative` function
* tests/unit/db/test_traits.py: Move `export_informative` function tests here
* tests/unit/test_partial_correlations.py: Remove `export_informative`
  function tests

  The `export_informative` function relates more to the traits than to the
  partial correlations, and could find use in more than just the partial
  correlations stuff. This commit moves the function to the more
  traits-specific `gn3.db.traits` module.

Subject: Implement `control_samples` function as is in GN1

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/partial_correlations.py: Implement `control_samples` function
* tests/unit/test_partial_correlations.py: add tests for `control_samples`
  function

  Implement the function `control_samples` and make it mostly bug-compatible
  with the `web/webqtl/correlation/correlationFunction.controlStrain` function
  in GN1.

  This implementation in GN3 does not do any calls to the database. It will
  rely on other functions to provide the data from the database to it.

Subject: Add typing. Simplify arguments.

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/non-clustered-heatmaps-and-flipping.gmi

* Add type-hints to the functions
* Merge the axis data and labels to simpler dict arguments to reduce number of
  parameters to the function.

Subject: Migrate `export_informative` function

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/partial_correlations.py: Implement a mostly, bug-compatible
  `export_informative` function as part of migrating the partial correlations
  feature over to GN3 from GN1
* tests/unit/test_partial_correlations.py: Implement tests to ensure the code
  work in a similar manner as that one in GN1.

From 679c3edd08453d2f1ef09b3461fd8d0b038b3adf Mon Sep 17 00:00:00 2001
From: Frederick Muriuki Muriithi

Subject: Move 'export_trait_data' to 'gn3.db.traits' module

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/db/traits.py: Move function `export_trait_data` here
* gn3/heatmaps.py: Remove function `export_trait_data`
* tests/unit/db/test_traits.py: Move function `export_trait_data` tests here
* tests/unit/test_heatmaps.py: Remove function `export_trait_data` here

  Function `export_trait_data` more closely corresponds to the traits and is
  used in more than just the `gn3.heatmaps` module. This commit moves the
  relevant code over to the `gn3.db.traits` module and also moves the tests to
  the corresponding tests modules.

Subject: Move `export_informative` function to `gn3.db.traits` module

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/db/traits.py: Move `export_informative` function here
* gn3/partial_correlations.py: Remove `export_informative` function
* tests/unit/db/test_traits.py: Move `export_informative` function tests here
* tests/unit/test_partial_correlations.py: Remove `export_informative`
  function tests

  The `export_informative` function relates more to the traits than to the
  partial correlations, and could find use in more than just the partial
  correlations stuff. This commit moves the function to the more
  traits-specific `gn3.db.traits` module.

Subject: Implement `control_samples` function as is in GN1

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/partial_correlations.py: Implement `control_samples` function
* tests/unit/test_partial_correlations.py: add tests for `control_samples`
  function

  Implement the function `control_samples` and make it mostly bug-compatible
  with the `web/webqtl/correlation/correlationFunction.controlStrain` function
  in GN1.

  This implementation in GN3 does not do any calls to the database. It will
  rely on other functions to provide the data from the database to it.

Subject: Implement `translate_to_mouse_gene_id` function

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* Migrate the `web.webqtl.correlation/CorrelationPage.translateToMouseGeneID`
  function in GN1 to GN3.
  This is a function that retrieves data from the database, and therefore uses
  a system outside of our code, therefore, the function does not have a
  corresponding unit test.

  This kind of function will probably need to be tested at the integration or
  system tests level, where we test that our code interacts correcly with any
  and all external systems that it should.

* Migrate:

  * `web.webqtl.correlation.CorrelationPage.fetchLitCorrelations`

  from GeneNetwork1.

  The first function creates and populates a temporary table with the

  The second function uses the data in the newly created temporary table to

Subject: Implement `partition_all` function

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* gn3/data_helpers.py: new function (partition_all)
* tests/unit/test_data_helpers.py: tests for function
  `gn3.data_helpers.partition_all`

  As part of migrating some functions that access the database, this commit
  extracts generic processes that can be accomplished on data, and implements
  the `partition_all` function, that is equivalent to Clojure's
  `partition-all` function.

Subject: Start implementation of `fetch_tissue_correlations` and dependencies

* compare_tissue_correlation_absolute_values: New function. Complete. Used for
  sorting of tissue correlation values
* fetch_symbol_value_pair_dict: New function. Complete. Maps gene symbols to
  tissue expression data
* fetch_gene_symbol_tissue_value_dict: New function. Complete. Wrapper for
  `gn3.db.correlations.fetch_symbol_value_pair_dict` function
* fetch_tissue_probeset_xref_info: New function. Complete. Retrieves the
  Probeset XRef information for tissues from the database.
* correlations_of_all_tissue_traits: Stub. Dependencies not completed yet.
* build_temporary_tissue_correlations_table: Stub. Dependencies not completed
  yet.
* fetch_tissue_correlations: New function. Incomplete. This function calls (a)
  stub(s) function(s) which is/are under development still.

Subject: Move the function to computations module

Issue:
https://github.com/genenetwork/gn-gemtext-threads/blob/main/topics/gn1-migration-to-gn2/partial-correlations.gmi

* The function `batch_computed_tissue_correlation` is a pure computations
  function with no expressions accessing the database, as far as I can tell,
  therefore, this commit moves the function over to the
  gn3.computations.partial_correlations module that holds the pure computation
  functions.

  Migrate the `cal_tissue_corr` function embedded in the
  `web.webqtl.correlation.correlationFunction.batchCalTissueCorr` function in
  GN1 and implement tests to ensure it works correctly.

Subject: Move `correlations_of_all_tissue_traits`

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 (`correlations_of_all_tissue_traits`).
* gn3/db/correlations.py: delete
  function (`correlations_of_all_tissue_traits`).

  Move the function to `gn3.computations.partial_correlations` module and
  comment out the db-access code.
  Rework it to receive, as arguments, the data it previously fetched from the
  database, and add comments on future rework to get the function working
  again.

Subject: Specify 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.

Subject: Implement `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.

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.
