[AMBER] PSF file, atom radii and chamber

Dear all,

I have trajectories in dcd format with PSF topology files and I would need
to use cpptraj of AT12 to calculate the SASA, either with surf or molsurf
program.

Both surf and molsurf require the atom radii parameters in the
topology/parameter file,
and PSF files do not contain them.

I have been trying to convert PDB and PSF files into crd and prm files using
chamber, so as to include the atom radii, but the program stops producing
the error shown in the attachment.

Any hint/help on how to work around this will be really appreciated.
Thanks a lot in advance.

ATB,
