A problem about 3dcopy

Hi, everyone

I meet a problem when I try to transfer .hdr files to nifti files. In my data, 240 hdr files are included in each subject. Then I try to use 3dcopy to thansfer them together , but failed.

FATAL ERROR: 3dcopy only takes one input AND one output filename after options.

So, Is there any body could tell me that how can I thansfer all these hdr files to one nifti file? Then I can continue to process it by afni.

Appreciate to receive your kind reply!


Maybe 3dTcat is what you want.

Thanks you so much! I will try it now! B-)
