I installed lcmodel following the tutorial LCModel's home page
But when I try tu run the model using lcmgui I get an empty .ps file and this error message:
It’s not clear how far you came in the installation/tutorial, are you trying to do a “test run”, or using your own data already?
If using your own data – could you please give a little more detail about your setup (eg, data format, and contents of the “control file”, which may be shown just before the run)?
Do the standard test runs work as expected? See chapter 4 of the LCModel manual, perhaps 4.3 is the most direct: try running $HOME/.lcmodel/bin/testrun and check for output in $HOME/.lcmodel/test/output/test.ps
