[gmx-users] does editconf follow pdb rules?

In my hands, the command

editconf -f input.gro -o output.gro

does not follow the PDB rules as regards the residue name. W from the
.gro file (obtained by

genconf -f water.gro -nbox 2.5 2.5 2.0 -0 out.

where water.gro is from MARTINI web page, is placed correctly as atom
(column 14, i.e., right justified), while W as residue is placed in
column 20, i.e. right justified. W as residue should be left justified
in column 18.

If this error reproduces in your hands, it was probably responsible
for my troubles in building a CG system according to my "graphic"
procedure. My system treats differently W at 18 or 20 column and my
explain the problems posted a couple of days ago in reply to demands
by Justin.

Thanks for checking
