Dear all,
I am sorry if anyone is getting this email twice. I have been trying to
use new implicit solvent feature in recently released NAMDv2.8b1 (64 bit
Linux_X86_64 binary and ran using ++local option). I tried default options
suggested in NAMD user's guide (
http://www.ks.uiuc.edu/Research/namd/2.8b1/ug/node31.html), and have tried
both with and without PBCs, but I start getting some weird output right at
the beginning of these runs. No dcd files are updated after two or three
frames. The kind of output I get during initial minimization steps looks
like as given below.
The input files for this run can be downloaded from the following link:

Any help would be great. Thank you so much.
