This page shows example data available at: https://github.com/nifm-gin/Data_Test_MP3
First, one needs to open a project. In the File menu, click on Open a project and select the folder containing your project, as defined at the importation (link).
Once it is done, one can display an image by selecting its sequence name and clicking on the Load button. In the common case of 3D images, one can navigate through the slices thanks to the scroll wheel or the scrollbar under the image. For 4D and 5D images, 2 scrollbar (only available when needed) allows to navigate through those dimensions.
One can display up to 4 images together by selecting 4 sequence names before clicking on Load. Overfly images with the mouse cursor displays the value of the voxel overflown in each image.
Click on Scans above the Sequence list displays the list containing the available ROIs. When at least an image is loaded, one can display on it up to 4 ROIs by selecting them and clicking on Load. A colored line contours the voxels contained in the ROI. In addition, statistics such as mean and standard deviation in the ROI are displayed near the images.
One can change the view from axial (default) to Saggital or Coronal by clicking on the related buttons above the images.
One can modify the displayed colormap by selecting another mode on the menu under the Load button.
One can modify the contrast of the displayed images by right clicking on the image and moving (without release the click !) the mouse cursor. When displaying several images, one can apply the same contrast to all the images by clicking and moving on the scroll wheel instead of the right click.
The Parametric Response Map (PRM) mode is useful to study longitudinal data, ie when a scan exists for at least 2 timepoints of a patient.
Click on the PRM button above the images to enable it. Then one can load a scan that exists in at least 2 timepoints of the selected patient. Two images are then displayed, and a scrollbar under the image on the left allows to navigate through the timepoints. It is then allowed to display images of 2 different timepoints next to each other.
