Dear All,<br>
Hi! I 'm using Charmm-gui to generate an empty membrane pdb and toppar, i
managed to get the charmm topology from toppar directory. With that,
I'm trying to put additional lipid topology from charmm-gui into
/charmm27.ff/lipids.rtp (gromacs4.5.4) for my empty membrane. But with
pdb2gmx, it failed to recognize the residue type with the error "Residue
not found in residue topology database".<br>
May i know in the rtp file format, is the spacing crucial in order for gromacs to process?<br>
<br>
thank you in advance.<br>
<br>
<br>
best regards,<br>
