Hi developer,
I'm trying to using the practice demo data downloaded from https://zenodo.org/record/5103099/files/demo.tar.gz, and I have successfully installed the latest version of xpore version 2.0.
When I came to the step of dataprep, I kept getting the same ERROR and could not proceed, it seemed that something wrong happened to the index.

My working directory:
~/bioinfo/xpore_practice/demo/data/HEK293T-WT-rep1

The running command:

xpore dataprep \
--eventalign nanopolish/eventalign.txt \
--gtf_path_or_url demo.gtf \
--transcript_fasta_paths_or_urls demo.fa \
--out_dir dataprep \
--genome

And then came this ERROR:
/home/huangkx/miniconda3/lib/python3.9/site-packages/pandas/core/frame.py:3607: SettingWithCopyWarning:
A value is trying to be set on a copy of a slice from a DataFrame.
Try using .loc[row_indexer,col_indexer] = value instead

It would be grateful if you could give me some advice on solving this problem. Thanks for developing this nice tool.
