Hello experts, 

Some colleagues used BrainVoyager to analyze their data and I’m using FSL. They reported in their paper that they ran group ICA and obtained Z-values from the individual maps to indirectly measure functional connectivity. They also used the Z-values to assess group differences with an ANOVA on the Z-values.

With FSL where could I find these data?



As ICA on fMRI data intrinsically extracts patterns of coherent neuronal activity (i.e. networks), Z values, obtained from individual maps, can indirectly provide a measure of functional connectivity within the network [48].

For each network, between-groups differences were assessed by means of a voxel-wise one way ANOVA on Z values, obtained by individual ICA group maps, and as clusters of interest were considered only those included in the nodes of each ICNs.
