I am doing a simulation on Hemoglobin molecule.
In the topology file for Heme (toppar_all22_prot_heme.str), what is the difference between PHEM and FHEM.
I am little confused as to when the FHEM and PHEM has to be used.
For DEOXYHEMOGLOBIN, i am using only PHEM to pacth HEME to proximal Histidines.
Kindly let me know ...
