Dear Dr. Zhu,
Thanks for your reply. I did carefully read the manual, especially the section you suggested, before I posted this message. And I am totally for sure that the VASP binary is available at the running folder.(which vasp yields the correct vasp path). I carefully examined this issue after receiving your reply. I found that the submitting script(e.g. myrun) is correctly located at the CalcFolder# and the PBS setting in myrun are correct as well. But the error " Error reading item 'VCAIMAGES' from file INCAR." shows up. This is because there is not VASP input files for the calculation in the current running folder. So, the problem now is USPEX will not go the CalcFolder# but submit the script at the root folder of EX01.
Is there any wrong with the code "[a,b]=unix(['qsub myrun'])" ? I am not very familiar with matlab string programming.
Thanks
Bingo
