Hi All,
I have a question regarding MRview’s fixel based display. This is a rat brain study and I have compared the fixel maps from 2 groups. One group of animals with hypertension and the other without. After running “fixelcfestats” I displayed the entire fixel map of one of the uncorrected pval datasets. This displays the entire range of all the fixels nicely. When I go to threshold (by 1-0.95=0.05) I find a subset of the fixels “survive” … but what is interesting is that the scale bar is reset to show only the range of the fixels that were “statistically significant.” I did not anticipate that MRview would reset the ranges based on what survived after applying the significance threshold if thats indeed what is happening. The truth is I dont know what MRview is doing. If someone could tell me if my guess is correct or on the right track or totally off, I’d greatly appreciate it.
thank you
