Issues when running model 2

[GilbertoPPereira]

Hello!

I was trying out the code and had an issue with model 2 (the hybrid method).
I ran the example peptides in pep.fa and it returned the following error:

Traceback (most recent call last):
File "/home/gpereira/miniconda3/bin/toxinpred2", line 8, in
sys.exit(main())
^^^^^^
File "/home/gpereira/miniconda3/lib/python3.12/site-packages/toxinpred2/python_scripts/toxinpred2.py", line 355, in main

df3 = df3.append(df2.loc[df2.Subject==i][0:5]).reset_index(drop=True)
^^^^^^^^^^

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
AttributeError: 'DataFrame' object has no attribute 'append'. Did you mean: '_append'?

It looks something easy to fix by the user, but I wanted to bring it to your attention.

Best,
Gilberto
