Hi, There isn't currently a good way to display probtrackx results in the 3D mode. You can try clicking the "I" button and setting the image type to Mask/Label or Statistic, as either of these will be displayed, and you can see which you like better. I always have to reload the 3D window if I want to show these things. You should read the page about the 3D viewer to learn about all of the features currently available: http://www.fmrib.ox.ac.uk/fsl/fslview/3D.html Peace, Matt. -----Original Message----- From: [log in to unmask] [mailto:[log in to unmask]] Sent: Monday, October 15, 2007 9:20 AM To: Matt Glasser Subject: Re: [FSL] DTI processing Hi Matt! Thanks yeahh! It is working. But already the next problem: I saved some fibers in a nii.gz file. Those aswell I can visualise nicely in fslview 2D (red) BUT in 3D I dont see anything -neither with the opriginal nor with the (-mul 1000) one (cf attached screen shot). Maybe you know that problem also? ;-) Cheers, Markus Quoting Matt Glasser <[log in to unmask]>: > Try using fslmaths <data_FA> -mul 1000 <data_FA_mul1000> to multiply the > data by 1000.
