Thanks for your prompt reply. I am running csh and i have the suggested line in the .cshrc file. When I type: # hosttype i get the reply i486-linux when i type simply: #mod4 (with nothing else) i get /usr/local/bin/modeller4/bin/mod4: hosttype : command not found /usr/local/bin/modeller4/bin/mode: /usr/local/bin/modeller4/bin/mod_: no such file or directory. Have I installed the program in the right directories? I just copied the zipped archives to /usr/local and did whatever is written in the installation procedure. No error is generated till the end. But ./Run_tests produces the same errors: ./run_tops1:mod4: command not found Lutfullah -----Original Message----- From: Andrej Sali <sali@rockvax.rockefeller.edu> To: Lutfullah Kakakhel <seen@paknet2.ptc.pk> Cc: modeller_usage@salilab.org <modeller_usage@salilab.org> Date: Thursday, October 15, 1998 11:32 AM Subject: Re: Modeller on linux >Please define > >setenv HOSTTYPE i486-linux > >in your .cshrc file. > >Best, Andrej > > >> Lutfullah Kakakhel wrote: >> >> Hello, >> >> I just subscribed to the list and have the following to resolve: >> >> 1.
