In the fixed atoms commands:

"fixedAtoms on
fixedAtomsFile fixprotein.pdb
fixedAtomsCol B"

What does B stand for? I did this:

"set all [atomselect top all]
set fixatom [atomselect top "protein"]
$all set beta 0
$fixatom set beta 1
$all writepdb fixprotein.pdb"

to get the file with beta values, but the atoms with beta=1 ended up moving in the simulation anyway, so I was wondering what could have gone wrong.

I appreciate any help.

Kind regards,
