Re: [caret-users] Issue with displaying voxel intensities
Hi Rickert, Assuming you used File: Open Data File: type = Volume Anatomy File, you should see a normal T1w image. If you see solid white, then please upload the volume here, so we can try to replicate the problem: http://pulvinar.wustl.edu/cgi-bin/upload.cgi Donna On Jun 18, 2014, at 12:32 PM, "HINDRIKS, RIKKERT" wrote: > > Dear all, > > When I load a T1-weighted scan into Caret, the image looks like a mask, that > is, all white voxels covering the brain.

[caret-users] Issue with displaying voxel intensities
Dear all, When I load a T1-weighted scan into Caret, the image looks like a mask, that is, all white voxels covering the brain. The voxel intensities themselves are, however, nicely distributed and the grey and white matter peaks are clearly visible. Also, the intensities are normalized between 0 and 255. This problem does not occur when I view the scan with MRIcron or SPM. Does anyone know what is going on here? Thanks alot, Rikkert ___ caret-users mailing list caret-users@brainvis.wustl.edu http://brainvis.wustl.edu/mailman/listinfo/caret-users
Re: [caret-users] Brodmann areas 13-16 - Insular cortex
Hello Milan, Years ago, I generated the Brodmann surface-based maps in Caret by manually estimating areal boundaries on a surface-based atlas using as a reference the classical Brodmann drawing of a right hemisphere (reprinted in Polyak, 1947). Because this illustration did not include insular cortex, these areas were omitted from the surface-based parcellation. Several other parenthetical comments that you and others might find helpful: 1) The Brodmann areal boundaries on our surface-based atlases are only crude approximations, because Brodmann did not indicate their location within sulcal cortex. 2) Human cortical parcellation is a very active research arena. We have made available surface-based parcellations based on architectonics that cover about 1/3 of cortex, along with resting-state fMRI parcellations that span all of cortex. 3) FYI, Caret software is being maintained but not developed further. My lab is currently focused on continued development of Connectome Workbench (http://www.humanconnectome.org/software/connectome-workbench.html). Workbench performs most of what Caret can do (but better!) and has many additional visualization and analysis features. Caret spec files and data files can be imported into workbench-compatible format.
