Dear FSL experts,
I'm new to dual regression, and tried a group comparison with small samples (8 patients vs. 8 controls). 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:
**********
/usr/local/fsl4.1.8/fsl/bin/remove_ext: fork: Resource temporarily unavailable
ERROR: Program failed
An exception has been thrown
number of rows in design matrix doesn't match number of "time points" in input data!

For 2 ICs for which neither stage 2 nor 3 files were created:
**********

FSL4.1.8 is installed on Mac OS X snow leopard (64 bit mode). SGE is also installed, which works normally for other programs which utilize SGE like tbss and randomise.
Interestingly, these errors did not occur when I tried with another Mac (snow leopard (32 bit) with the same version of SGE), installed with FSL4.1.6. Can anyone figure out the cause of these errors?
Thanks a lot in advance,
Jun
