Hi all
I wonder if anybody has been using Pass to measure free volume: I got these
errors:
 
-Error:  Found an odd element (B) on atom #13454.  Hydrogen radius assigned.

Suggestion: Do I have to remove all the dummies?

-Segmentation fault
Suggestion: I use trjconv to get a pdb; is it possible that I am doing some
mistake in the conversion?

Thanx

Yes.

make an index file, it will have a suitable group for it.
