Dear CONN experts,

I am running a seed-to-voxel analysis in CONN and wanted to clarify the following points:

- is the band pass filtering carried out as the last step (unless chosen the simultaneous option)?

- I read in the manual that the dimensions in the confound tab represent how many temporal components are used, but I am wondering what is the effect of changing this (increasing/decreasing dimensions) on the denonising process?

- In the case of resting state what is the meaning of the 'effect of rest' confound?

- Finally, in the first level analysis a threshold 0.25 is set. Is there a reason for choosing this specific threshold?

Sorry for the many questions. I am really looking forward to hearing your advice.

Thank you,
Kind regards,
Bianca De Blasi
