Did you get the files from the MacKerell web site? I thought we'd fixed that OSP bug.
Yes, downloaded it today again cause I accidentally deleted the "conversion scripts" so I am sure it is from the MacKerell web site.
Just change the OSP to OSLP for those 2 phosphate O atoms in the old definitions of POPC and DOPC in the stream file.
Yep, I changed them already, but thought it would be of interest. But since I was tinkering with NAMD I was not shure if it was my fault or really a "BUG"
The convenience of NAMD usage was not a consideration.
