Re: AW: glycosaminoglycan with GLYCAM06 in amber format

Dear Norman and Felipe,

Many thanks for your replies.

The problem was indeed the specification of the SCNB and SCEE parts
for oligosaccharides.
By removing them and specifying the related values in the configuration
file, NAMD works fine.

Currently I am simulating the lone saccharide in water, so no problem
in removing
them.
But then I will have to simulate the saccharide together with a protein
and in that case I will need to specify mixed values for SCNB and SCEE
parameters.

Therefore I hope by the time I will be done with the lone glycosaminoglycan,
NAMD will be updated to read those parts in Amber topology files.

Best,
