Fwd: parseFEP domain error

Hello
As, in my hands, parseFEP fails to call imagemagick when both frwd and back
PEF are submitted (while it works when frwd alone is submitted), is there
any described way to reconstruct from the log files all graphics ? From
what I could do to this regard, grace plots from ParseFep. do match.

Thanks for help

Hello:
With frwd.fepout parseFEP invokes imagemagick, providing graphics besides
tables.

With frwd.fepout + back.fepout imagemagic only provides
entropy.log
gc.log
ParseFEP.log

not invoking imagemagick, while reporting the error:
domain error: argument not in valid range

SOFTWARE USED: VMD 1.9.3 on debian 9 (stretch) amd64 with XFCE

all imagemagic programs are on the path:

show /usr/bin with the various programs
francesco_at_vaio64:~$ dpkg -L imagemagick
