Hi Values in any of the rendered* files are _not_ Z-stats hth Christian On 18 Jan 2011, at 18:37, carlos silva pereira wrote: > I'm using FEAT, and the discrepancy's are relevant (e.g. 3.41 and 3.59). > Meanwhile I realized that I only see these differences if I open a rendered_thresh_zstat file in FLSVIEW, and not in a thresh_zstat file... > > > 2011/1/18 Reza Salimi <[log in to unmask]> > Carlos, > Are you using your own script or it is a FEAT (or another standard FSL) report/output file? > Anyway, I cannot think anything else that might go wrong really (as long as you are using the scripts/commands correctly and comparing the things that truly correspond to each other). I also assume that what you mean by discrepancy is not some difference that could be cause by Z-stats having different precisions (e.g., 2.38 and 2.4 is not what you mean, right?). As a last solution, I can ask you to please upload your coordinates text file and Z-stat volume and send us the ref # so we can check it ... > Cheers > > > On Tue, Jan 18, 2011 at 4:13 PM, carlos silva pereira <[log in to unmask]> wrote: > Hi Reza, > yes, I'm sure.
