RE: 2nd level error: dot indexing not supported for this variable type

[color=#000000]Sorry about this, I am trying to replicate this error condition, could you please check in your second-level results folder, where there will be a file named "spmF_mv.nii", whether another file named "spmF_mv.json" also exists, and if so, could you please send me that file to see if that helps me figure out what the issue might be here?[/color]

[color=#000000]Thanks[/color]

[color=#000000]Hi Alfonso,[/color]
[color=#000000]I am also experiencing this same error. It occurs when I am in 2nd level ICA. I select AllSubjects, then a second level covariate and when I switch the Between-subjects contrast to Effect of second level covariate, this error pops up. It then hangs when I attempt to stop the process. There is a file named '[/color]spmF_mv.json' in the results folder. I am attaching that here to assist finding the issue (unless you have already resolved this and I'm just not seeing the response in the forum). 
Thanks! Jennifer
