I am trying create a .psf file containing a cis peptide bond using the CISP
patch (with the latest toph19.pep and topallhdg.pro files from Michael
Nilges' group) in X-PLOR 3.1 as follows...
patch cisp
reference=-=( resid 10 )
reference=+=( resid 11 )
end
...however I keep getting the error message...
%PATCH-ERR: improper +HN +N -C -CA not found
%PATCH-ERR: improper +N +HN -C -CA not found
Does anyone know what might be causing this problem?
Thank you in advance for any help,
yours sincerley, Jamie Fletcher
