lh rh midline and mixed. The structure of your directory should be like this:STN_lh.nii.gz is not necessary. This is especially not intended, if the same structure appears in both lh and rh subfolders. In that case, the filenames should be identical. Place structures that exist only once in the brain (such as the hypophysis) or midline structures (like the fornix) into the midline subfolder. In case you have one NIfTI file for a bilateral structure (such as one file showing left and right STN) into the mixed subfolder.Render 3D and press Run. The first run takes long, be patient. The reason is that Lead-DBS needs to aggregate all information into a single file (atlas_index.mat) and creates a gray matter mask for VTA calculations (gm_mask.nii.gz).labeling atlas and then use the ea_labeling2atlasfunction to convert the file into a Lead-DBS atlas.labeling into an atlas, now runea_labeling2atlas('my_atlas');/atlases subdirectory. Usually, you can delete the .nii and .txt files from the /labeling folder after converting them to an atlas.Render 3D and press Run. The first run takes long, be patient. The reason is that Lead-DBS needs to aggregate all information into a single file (atlas_index.mat) and creates a gray matter mask for VTA calculations (gm_mask.nii.gz).ea_atlas2labelingfunction, as well. However, be aware that since the two formats have different capabilities and limitations, converting from one to the other isn't always straight-forward and results should be carefully checked.ea_atlas.index and gm_mask.nii.gz. The former can be modified (using MATLAB) to change colors of the atlas or to group entries to "presets" that can be easily toggled on or off. For instance, you may take a closer look on the DISTAL (Ewert 2017) in the 3D viewer to understand what possibilities are there. In the Atlas control figure, you can choose useful presets to visualize (such as Primary DBS targets. By choosing either STN: Solid or STN: Subzones the STN will be shown as a single structure or divided into motor, associative or limbic functional domains.atlas_index.mat file of the DISTAL atlas into MATLAB:atlases.defaultset ). The "default" entry can be absolute (meaning the preset will only show structures defined in the show entry and hide structures defined in the hide field) or relative (in which case the currently visible set of structures will not be altered if not explicitly mentioned).atlases.colors fields and the colormap to use by adding an atlases.colormap field (if not already present). For instanceatlases.colors ascendingly from red over white to blue.
