Hi Giovanni,
This looks like two bugs. The first is the documentation incorrectly stating -gamdlog instead of -gamd and the second is an actual bug in the code with how the command line is handled when GaMD is active. Thanks to Irfan Alibay for spotting this. We'll get a bugfix added as an update on the AMBER website to fix this.
In the meantime you can try editing the following:
src/pmemd/src/get_cmdline.F90 (around line 270)
call getarg_wrap(iarg, amdlog_name)
amdlog_specified = .true.
else if (arg .eq. '-gamd') then
call getarg_wrap(iarg, gamdlog_name)
gamdlog_specified = .true.
else if (arg .eq. '-scaledMD') then
iarg = iarg + 1
call getarg_wrap(iarg, scaledMDlog_name)
becomes
call getarg_wrap(iarg, amdlog_name)
amdlog_specified = .true.
else if (arg .eq. '-gamd') then
iarg = iarg + 1
call getarg_wrap(iarg, gamdlog_name)
gamdlog_specified = .true.
else if (arg .eq. '-scaledMD') then
iarg = iarg + 1
call getarg_wrap(iarg, scaledMDlog_name)
Then recompile.
All the best
Ross
