Dear Steve,
Thank you for your advice.

This means there are something wrong with the job scheduling of SGE?

I repeated melodic and dual regression from the start several times, all ended with the error messages of same kinds, though the errors occured for different ICs... Anyway I will ask my system administrator, and will post again if there are problems.
Happy New Year!

Unless you understand the details of what's in the dualreg script well, it's probably easiest to restart this analysis from scratch.

After finishing melodic I had 36 ICs, and performed dual_regression script, but dr_stage2_ic[#IC] files were not created for 2 ICs. For stage 3, there were no dr_stage3_ic[#IC] files for 24 out of 36 ICs (these 24 include the 2 ICs above). I've got the following error messages for 22 ICs:
