Manual preprocessing with Pandas>1.4+

[bpr4242]

Description of the bug

Hi Zewen! Great package I really have been enjoying it as I try to prepare a pipeline for some mouse scRNAseq with BCR/TCR paired libraries. I comment here to say that in reference to #180 where you enforce pandas<1.5 in your singularity environment, it seems that the issue lies with the new requirement that Pandas>1.5 raises a Value Error when an index is defined by a set.

Minimal reproducible example

import dandelion as ddl
sample = 'path/to/fasta'
ddl.pp.assign_isotypes((sample),org= "mouse", plot=True, save_plot= True)

The error message produced by the code above

ValueError                                Traceback (most recent call last)
----> 1 ddl.pp.assign_isotypes((samples[0]),filename_prefix=bcr_filename_prefixes,org= "mouse", plot=True, save_plot= True)

For the time being I am cloning my conda env and downgrading pandas/numpy to confirm the problem is fixed.

hi @bpr4242 thanks for the interest in this package! Actually I just updated the pypi version to 0.3.2 yesterday and it included an automatic fix by dependabot

• #264

So if you reinstall and use pandas >=2, it should still work

[bpr4242]

Perfect! Working well now, thank you!
