I 'm talking about the pre-surgical, whole brain. Using a fixed volumetric grid of 5mm, and then estimating ' from subject anatomy' the atlas Shaefer which corresponds to a specific grid that I used(whole brain 5mm), I obtain less than 400(397 ) or 593 (instead of 600) ROI that I would have have estimating the -cortical sources& cortical scouts. I tried to use Schaefer(400-600) in order to have higher parcellation and define better the post-surgical zone removed. Please check the new tutorials and make sure you work with an updated version of Brainstorm. Many new tools were added recently in Brainstorm to deal with anatomical atlases (and many more will be added added next year). Search the forumor read the file header for help:

To convert indices between surface, volume grid (GridLoc matrix), and source file, you can use the function bst_convert_indices.m. The source indices of all the scouts are available in the cortex surface: Is there a function inside bst where I can easily associate the source location and the atlas definition name ? If you need help with this part, please post screen captures illustrating your issues (showing the files in the database, the volume parcellation, the process options.) Schaefer ) the number or regions misses some ROIs( I'm not sure if a more parcellated volume is needed, ,I tried the 5mm as default, as I wanted to have quick results) Using more parcellated atlases as defined in CAT (i.e. My question is regarding the atlas correspondence. I would like to have a clear definition of the resected zone. Is there a function inside bst where I can easily associate the source location and the atlas definition name ?It is clearly plotted in the figure but I would like to have access to this correspondence. Schaefer ) the number or regions misses some ROIs( I'm not sure if a more parcellated volume is needed, ,I tried the 5mm as default, as I wanted to have quick results). The volume space seems more suitable as I can define by myself the grid, coregister the images and extract t the remaining source points on the same grid. In case of cortical space, the definition of the removed scout is not easy as the segmentation of post-surgical mri can have errors and defining well the resected zone is not easy. My question relates to the definition of the source space that will be subject specific. I'm studying several patients pre/post surgery. Each person always works with her/his own copy of the data set within her/his own environment of ATLAS.ti.Hi all, my question is related to the extraction of virtual channels and atlas correspondence. See Working with ATLAS.ti Libraries.ĭocument libraries CANNOT be shared. The location of where ATLAS.ti stores project related data can be determined by each user. If document editing is necessary, this needs to be done by the project administrator in the Master project!

If they do, the edited documents cannot be merged, and you end up with duplicates. Otherwise, the documents are duplicated or multiplied during the process of merging. If all team members should work on the same documents, it is essential that only the project administrator is setting up the project adding all documents. A good time for doing this is after merging and before creating the new Master file. If new documents need to be added to the project, this needs to be done by the project administrator. Mary exports the new Master file and distributes it to all team members. The project administrator merges all sub projects and creates a new Master file. To combine the work of all team members, each team member creates a project bundle file and sends it to the project administrator. This means creating a project bundle file .Īll team members import the project bundle file and begin their work. The project administrator saves the project and exports it. The project administrator adds documents to the project and possibly a list of codes. The project administrator sets up a Master project.
