create_batch_iterator that associates files with exact matching

[michelbotros]

For some file keys I am running into problems with associations. For example when the following files are in my data.yml:

DATASET5-12345_HE-I.tiff DATASET5-12345_HE-II.tiff DATASET5-12345_HE-III.tiff

In this case associate_files() with exact matching is required. Is it possible to add the functionality of requiring exact matching to associate files to the create_batch_iterator function?

At some point it calls associate_files() in https://github.com/DIAGNijmegen/pathology-whole-slide-data/blob/c4ea347c1b25cc212e26a4f8f8b5bdcc27ae5688/wholeslidedata/source/associations.py#L55

It's default setting for requiring an exact match is False. I think I'd be useful to be able to call create_batch_iterator with requiring an exact match.

Let me know what you think about adding this or if you know a workaround solution!

Dear Michel Botros,

Yes, this feature is already implemented. You can add it to your user config e.g.,:

wholeslidedata:
    default:
        associations:
            exact_match: True

Please let me know if you still encounter problems or have any other questions.

Best wishes, Mart
