After downgrade pandas to version 1.4 I've replaced the Error for a Warning, however I can see another error

illa/STAR_index_virus --outFileNamePrefix_human human --nthreads 12 --filename_output VIRTUS.output.txt 

/home/me/VIRTUS2/bin//VIRTUS_wrapper.py:198: FutureWarning: Passing a set as an indexer is deprecated and will raise in a future version. Use a list instead.
  df_cov = df_cov.loc[list_index]

    df_cov = df_cov[df_rate.columns]
AttributeError: '_LocIndexer' object has no attribute 'columns'

How can I fix this one?

Hi patrick,

I'm testing VIRTUS_wrapper.py using pandas==1.3.5. To check whether the problem is caused by your input or environment, could you test VIRTUS_wrapper.py using the same input.csv as in https://github.com/yyoshiaki/VIRTUS2#wrapper-for-multiple-analysis ?

Hi @yyoshiaki, After a long wait the error was the same for the dataset you suggested, take a look below, seems like to fail only in the final process (heatmap generations):

Sorry for not getting back to you sooner. I had a conference last week. It looks like a version incompatibility for some packages. I will try to reproduce the issue. You tried the wrapper with python3.10 and pandas 1.40, right? I tested it with python 3.8.10 and pandas 1.3.5 and no error occurred.

[yyoshiaki]

Maybe I solved the problem. I pushed the updated VIRTUS_wrapper.py in branch 2.0.2.

Can you git clone the latest repository and change the branch to v2.0.2 or just download https://github.com/yyoshiaki/VIRTUS2/blob/v2.0.2/wrapper/VIRTUS_wrapper.py ?

Dear @yyoshiaki It worked very well, thank you very much. Could you take a look at this issue?

All best Patrick~
