Update threshold.py

[ANRudrapatna]

Issue:

• maxatac predict expects the following column names in a cutoff file:

  • 'Monotonic_Avg_Precision', 'Monotonic_Avg_Recall', 'Standard_Thresh', 'Monotonic_Avg_log2FC', 'Avg_F1'.

• However, maxatac threshold outputs a file with the following column names:

  • 'Monotonic_Precision', 'Monotonic_Recall', 'Threshold', 'Monotonic_log2FC', 'Monotonic_F1'.

• When these columns are not available, maxatac predict will not output a BED file of TFBS predictions, even when a cutoff file and type are specified by the user.

Fix:

• I changed the column names in line 143 to correspond to the expected column names for maxatac predict.

I tested this change to ensure it works with v1.0.6 of maxATAC. A BED file of predictions is now outputted when a cutoff file and type are specified by the user.
