Dear FSL experts, A very fool question: I am trying to re-run my MELODIC analysis with more subjects. I didn´t have any problem during the first time, but now I get the following error: /usr/local/fsl/bin/fslcreatehd tmpHeader filtered_func_data Incomplete or incorrect text: could not form header info FATAL ERROR ENCOUNTERED Incomplete or incorrect text: could not form header info while executing "if { [ catch { for { set argindex 1 } { $argindex < $argc } { incr argindex 1 } { switch -- [ lindex $argv $argindex ] { -I { incr arginde..." (file "/usr/local/fsl/bin/feat" line 310) -prestats Incomplete or incorrect text: could not form header info The data is already preprocessed and I am doing exactly the same that I did in my previous analysis, but I still have the same message. I tried to change the analysis, ran it with less subjects, change small parameters, check the images... still, the same error message. Any advice will be more than welcome!
