When I run the generated scripts from QwikMD, I notice in the log file this:

The total charge is specified in the RTF, but does "SKIPPING rtf SECTION IN STREAM FILE" also skip the
charge specification? Or does NAMD use the charges in the PSF file and it adds up those charges to the
total charge? I ask because my ligand is a +1 charge, and it needs to be +1 during the simulation. The partial
charges add up to +1, but does NAMD use the total charge from the RTF or the partial charges from the PSF? Thanks!
