Thanks a lot! ________________________________________ From: FSL - FMRIB's Software Library [[log in to unmask]] On Behalf Of Stephen Smith [[log in to unmask]] Sent: 22 July 2013 14:23 To: [log in to unmask] Subject: Re: [FSL] FSLNets colour coding and r2z transformation Hi On 22 Jul 2013, at 11:57, Lückmann, Helen (Stud. FPN) <[log in to unmask]<mailto:[log in to unmask]>> wrote: Dear experts, Having checked the script and output of FSLNets, I have two remaining questions. 1) After r2z transformation, do the values in the matrices correspond to z-values as in standardised z-scores (with a z-value of 1.645 corresponding to p = 0.05 one-sided)? If not, how can I interpret their significance? yes 2) How do the colours in the hierarchy-figure correspond to the strength of correlation (I'd like to add this information to my figures)? It seems that the scaling is relative to the maximum z-scores, but I could not figure out the exact algorithm. it's the default matlab colourmap - click on the Matlab colourbar button to see it Steve.
