Branko,
I am running ABF in NAMD 2.6. So I changed the following and ran it again.
"set ABFdir ./abf-1.8
source ./abf-1.8/abf.tcl"
with
"source ./abf-1.8/abf.tcl
package require abf"
but end up with the same error that is
FATAL ERROR: Setting parameter TclForces from script failed!
And i do have the abf folder in the current directory which has all the tcl
scripts. Please advice me further.
Thanks and Regards,
Jagan Mohan
