Dear Sir:

I encounter several problems when I first ran the model-default.top file
in the tutorial-model directory.

1: If I log in the tcsh with my home directory,I cannot run the command
"mod model-default".The reminder is "mod" command cannot be found.

2: If I log in the tcsh with root directory,I can run "mod model-default"
after I run "source ~/.cshrc".When I log out and log in again with my
home directory,the run "mod model-default",the error reminder is:
" /usr/local/bin/modeller6v1/bin/mod6v1: ./model-default.log: Permission
denied "

3: When I log in with root directory again, I only could run "mod
model-default" after I run "source ~/.cshrc" again.

So, my questions are:

<1> Should I run the "mod model-default" every time when I log in the
shell with ROOT?

<2> Should I run "source ~/.cshrc" each time before running "mod
model-default"?

The following is the login script of mine for your reference.
