FC parameter

Hi,

We have fMRI data from different sites with different parameters. I have preprogressed them separately using dparsfa. And then can I put them together as a group to analyse the functional connectivity?

Thanks.

Jane

The accaptable of the data is dependent on the purpurse/design of your study. 

If it's a case-control study, and the data was balanced between groups with respect to the scanning site/parameter, I think its ok for further analysis, such as FC and between-group comparison.

Thank you so much. But when I put the data with different paremeter in the folder named "FunARWCF", dparsfa can not read them, and keeps showing like "put the NIFT data in FunARWCF". I also try the data with the same paremeter the same way, it can work. So how can I  use dparsfa to analyse the FC in the group with different paremeter?

I don't think the report caused by the different scanning parameter of your data, since 1) your data has been already normalized to MNI space, 2)before 'run', deparsfa just check the name of your subjects' folder, not the parameter of your data.
So, please check the arrangment of your folder, and show it here.
