Hi Eleanor According to the peak search the 3 highest peaks on the chi=180 section are at: | 390.00 -52.26 180.000.49 | | 490.00 -73.73 180.000.47 | | 590.00 -66.55 180.000.44 | plus a lot of lower peaks on that section which are clearly in the

Ian - I read the log file - agree, you cant get much from the pictures.. But the peak heat of the translation vector is 50% od the origin - ie pretty strong.. And ditto for the rotation angles - all 50% of origin too But of course any set of rotation angles does not have to generate a closed rotati

Hi Fred, Since you're using CHARMM forcefield, another option is to use swissparam.ch . I don't know which system you're working on but I've recently used swissparam for multiple protein-ligand simulations. Best, Tushar. On Sat, 22 May 2021, 21:13 Murpholino Peligro, wrote: > Hi Fred.. > As a

Hi Fred.. As an alternative, not mentioned yet, you can use NAMD ( https://www.ks.uiuc.edu/Research/namd/). If I remember correctly it accepts the charmm force fields. I think the documentation is way better... they also have a mailing list ... As a plus... you can download a 'full' version without
