Hi Justin thank you again for this past answer and again I received this same error after correcting my later other coordinate file not matching topology. For this command I did not need to copy the lipids since to my understanding the command:
perl inflategro.pl system.gro 4 DPPC 14 system_inflated.gro 5 area.dat
should of generated the correct number of lipids. Below is a more detailed link to my issue (I freshly re-posted for other members to manage your time) and moreover I amended my system_inflated.gro to match the topol.top file but received more errors, thanks if you can help.
(I will try and google this exact error more since I could not find this particular error in the past forum.)
