No, I unistalled vmd 1.9.2 and installed VMD 1.9.1. Because in the
molfacture plugin of VMD 1.9.1, there is an option that when the user is
finished with changing the atom names, types and charges and is going to
write the PSF and PDB file, s/he can brows any parameter file.

Since the molcules we intend to inspect are new and complicated, they are
not included in C27 which is default of VMD. Therefore, I assumed that we
will be able to solve this defficiency by loading par_all36_cgenff while
writing pdb and psf files in molefacture. I tried this for two different
ligand [29 and 54 atoms] ;it did not work.

As a second try, following the recommendation of a vmd expert, I typed the
pathway of all the par and top files of C36 in a text file, proceeding each
line with STREAM:

stream C:\Users\zemami\Desktop\ETHA\toppar\00toppar_file_format
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all22_prot.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all35_ethers.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all36_carb.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all36_cgenff.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all36_lipid.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all36_na.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_all36_prot.prm
stream C:\Users\zemami\Desktop\ETHA\toppar\par_hbond.inp
stream C:\Users\zemami\Desktop\ETHA\toppar\param19.inp
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all22_prot
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all35_ethers
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all36_carb
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all36_cgenff
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all36_lipid
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all36_na
stream C:\Users\zemami\Desktop\ETHA\toppar\top_all36_prot
stream C:\Users\zemami\Desktop\ETHA\toppar\toph19.inp
stream C:\Users\zemami\Desktop\ETHA\toppar\toppar_all.history
stream C:\Users\zemami\Desktop\ETHA\toppar\toppar_water_ions.str

And in the molefacture write pdb and psf file, in parameter file brows, I
loaded this text file. this way also did not work.

I wrote all these to:

1. explain why we switched from vmd 1.9.2 to vmd 1.9.1.
2 to get advise from you about our problem with molefacture for complicated
compunds.

Sincerely Yours,
Zeinab
