Hi Stephen and Harry,
I have difficulty to use MELODIC with Multi-session temporal concatenation as well. I tried to give 2 runs of the same subject, I also tried to give 1 run of 2 different subjects. Both seems to have some problem at registration stage. I tried to turn off all the pre-processing options and do not provide any image for registration, the result still the same. It seems something wrong at the registration stage (the registration results missing 1 image) and there is no ICA component calculated.
Below is a log after I do 2 runs of 1 subject using Multi-session temporal concatenation. I am running MELODIC 3.10 on mac 10.5. Thank you for your help.
Sincerely,
