Running count metric & jump method OverflowError: cannot convert float infinity to integer

Hello @hongyeehh, I'm getting this error when running Count Metric & Jump Method:

Running count metric & jump method
Values less than or equal to 0 in data. Throwing out 0 or negative values

Here, I dropped the input files and the command I'm using:

Hi @caviri, thanks for the report. I was able to reproduce and fix the error.

The problem comes from here, where the calculated metrics contains 0, and the plotting function tries to plot the 0 in log scale.

This is now fixed by only taking the values larger than xmin (default to 1) for plotting. The filter has a negligible effect on the actual results.

Please check whether the error persists with the latest commit.
