Dear Freesurfers,
I have come across a problem with viewing the significant clusters on qdec display tab. When a particular query is selected after analyzing for a selected design there are multiple clusters of varying size which appear. This query when run (corrected) with Monte carlo simulation (at particular selected threshold ex;- 1.3 ),the display tab shows an inflated image with significant cluster at selected threshold and also there is an output in the terminal as well which gives data about the size,number of vertices etc of the output cluster Please correct me if I am following the procedure for multiple comparisons wrongly or going wrong in any part of analysis and correction for multiple comparisons.
However I have observed that sometimes,even though there is an output in the terminal (sometimes the cluster having almost as 1900-200 vtxs),there is no display of the cluster on the inflated image on the display tab. I dont know why this is happening,But I have seen this to be the case in a number of situations.
I would also be interested to know if there is any other alternate method for viewing clusters.Since the clusters on display images are absolute necessity for all reporting purposes . I hope to hear from you soon.
