Dear all,
Thank you for the responses. I tried the script again with "package require
namdenergy" and solved half of the problem I guess. However, the output now
looks like,
namdEnergy) Running
namdEnergy) namd-temp.namd
*couldn't execute "": no such file or directory*
I thought the error is coming from the parameter file I specified but the
log says the parameter file is taken into consideration. The error is there
even if I use the default parameter file. Looks like a minor thing but it
is still not working. Any insight is appreciated.
Thanks.
Monika
