Error in methratio.py

[luqman]

Hi,

I ran the following commands on methratio.py:

python methratio.py s_7_results.bsp s_7_methratio.txt hg19allChr.fa
wig=s_7_methratio.wig CG=false name=hg19.methratio

and i receive the following error:

Traceback (most recent call last):
File "methratio.py", line 94, in <module>
if seq[index] == 'T': #unmethylated
IndexError: string index out of range

Can you advise for a fix?

Thanks!
