ERROR when using tredreport.py

[alessia677]

hi!! I am trying to use your tool for analyzing HTT sequences. I think I correctly installed the program, since I have been able to use the first script without errors (tred.py). However, when I have to run the tredreport.py (using as input the .json file generated previously), I obtained this error:

Using 1 cpus to parse 1 JSON files
/media/sequentia/visitors/visitor4/HTT/tredparse/tredparse/tredreport.py:135: FutureWarning: '.reindex_axis' is deprecated and will be removed in a future version. Use '.reindex' instead.
tf = df.reindex_axis(columns, axis='columns')
TSV output written to out.tsv (# samples=1)

Maybe I am making some mistakes, have you any suggestions?

Thanks you,
