The pairs.dat and occupancy.xvg files are empty. When I  opened the occupancy.xvg by ConTexT ,the following results could be seen:"

Never used that script, so can't help you there.  However, before
using the script, does the hbmap.xpm file contain valid data that you
would expect the script to be able to process? i.e. is the input into
the script valid?  If so, then might be an issue with the script, so
contact that person that wrote it.  They have provided their email

Catch ya,
