Arterial Territory This zip file contains three arterial atlases (ARTERIAL1, ARTERIAL2, ARTERIAL1_WM-GM) corresponding to the atlases defined in Liu C-F, Hsu J, Xu X, Kim G, Sheppard SM,Meier EL et al. You are going to binarize the seed image so we can use it as a mask: fslmaths PCC-thr 0. This *_firstseg image shows the combined segmentation of all structures based on the surface meshes that FIRST has fit to the image. This is because there are lots of empty voxels in the image (because the data has been brain-extracted) that are affecting the calculation. If your two segmentations are called seg1. colourbar This module provides the ColourBar class, which generates a bitmap rendering of a colour bar. Try this out using FSLeyes to get a rough guess (in voxels) of where the centre of the brain is in the image and use the values when you call bet Open mean_f1samples in FSLeyes.

SSH/X11 - wxPython version If you are using ssh-X or ssh-Y to connect to a remote server, be aware that recent versions of wxPython (the GUI toolkit upon which FSLeyes is based) no longer support the GLX protocol FSLeyes allows you to choose between displaying your overlays in terms of one reference image, or displaying all overlays in world space. For publication quality (programatically reproducible) images you’ll likely use nilearn. Note that we are seeing the first volume of a time-series, and that we can flip through the images by clicking on the up or down arrows next to the “Volume” field in order to scroll forward or backward through the volumes. Because FSLeyes allows multiple views to be opened simultaneously, it needs to use multiple DisplayContext instances. Some of these are used for tutorials specific to MRIcroGL, such as the Iguana image, or any of the CT images. The contrast seems low between the grey and white matter, but this is because the blood vessels of the neck (indicated by orange arrows) are much brighter than the rest of the brain. 3 FSL is a comprehensive library of analysis tools for FMRI, MRI and diffusion brain imaging data.
