(unknown charset) Re: [AMBER] loadPdbUsingSeq command
Excuse me for the first part of my tleap script, this is clearly the mistake.
But my problem with loadPdbUsingSeq command still remains.
As Donald said I am using loadPdbUsingSeq command in tleap because I
want to take the middle part of my big enzyme for further calculations
and for that I need to leave these ends with open valences (I don't
want tleap to create charged termini or to add neutral protecting
So, as I thought, problem is number of characters in strings. Is there
a way to change this?
