Dear all
I am running keepbyz.pl script to remove unwanted
waters from hydrophobic core of lipid . I am getting problem in this
process. For this I follow the chris neale rule -

I have successfully completed all the step but getting problem in
completing last step i.e editconf step , in the last file
new_sequential_numbers.gro which is made by editconf unable to keep
solvent molecules which is present in "new_system.gro ". Also one
warning came during the last editconf process i.e-
WARNING 1 [file aminoacids.dat, line 1]:
Bad box in file new_system.gro
I am unable to understand why it shows Bad box in file "new_system.gro"
?. Can anyone help me to solve this problem.?
What does your "new_system.gro" have on the last line? Have you specified the
correct number of atoms on the second line of the .gro file so that editconf is
reading the correct line to determine box vectors?

I will be really thankful for that.
