One of the other users might know better, but it looks like your<br>
"min_lapw -p -so" command does not look right.<br>
<br>
I suggest you run in the terminal the command: min_lapw -h<br>
<br>
I'm not seeing an option for '-so' in the output from that command.<br>
<br>
Since you did not use '-j', it looks like the script uses "run_lapw -I<br>
-fc 1. -i 40" by default (whereas '-sp' should use "runsp_lapw -I -fc 1.<br>
-i 40" by default).<br>
<br>
For SO, you probably need to use the "-j" option:<br>
<br>
min_lapw -p -j "runsp_lapw -I -so -fc 1. -i 40"<br>
<br>
or it looks like there is the '-m' option that will extract force-input<br>
and execute mini (without JOB) and exit.<br>
