Hi,
This is my input file for calculating bilayer thickness in absence of peptide:
###### Input file and input file parameters
coord_file              md.gro
file_type                 gro

num_lipid_types        1
resname1                POPC
atomname1               P8
solvent                   SOL

###### Define the size and shape of the grid
box_size                solvent

conserve_ratio        yes
###### Define whether there is a protein embedded in the bilayer
protein                   no

P_value                 5.0
###### Define the desired output files and format
output_prefix           output
output_format          column
thickness                   yes
area                           no

I got 400 lines in one column in output file for average thickness
(calculated without peptide)

When running in Gnuplot I get following error:
splot 'output.frame1.20x20.average_thickness.dat' matrix using (1+$1):(1+$2):3
Warning: empty x range [1:1], adjusting to [0.99:1.01]


Please refer to Appendix A, section 2 of our GridMAT-MD manual, which explains the preprocessing necessary to open the file in Gnuplot, otherwise refer to the manual section describing the output_format keyword.

You can send GridMAT-MD questions directly to me; there is no need to fill peoples' inboxes with non-Gromacs questions.
