mask_explorer_1 - Matlab Tool for Dataset Exploration Suitablefor fMRI Group Analysis

Software mask_explorer_1 is written to explore fMRI datasets and to find inconsistences in fMRI data. mask_explorer_1 is suitable especially for group analyses. Inconsistent data (e.g. in form of missing data from single subject or revealing failed steps in preprocessing of fMRI data of some subjects) can lead to irrelevant conclusions. Software was written in Matlab (version 7.14.0.739 (R2012a)) and uses parts of toolbox SPM8 (version 4290). User can on left side of GUI load data (Load masks or cons) from several subjects (NIFTI). Loaded inputs are used to create parametric map. Its values show number of datasets with valid information. This map (GSBC) and group mask (GCMS) mask_explorer_1 saves. Several pseudocoloring modes, thresholding options and transparency options are available. ‘Load background’ loads background image (NIFTI). ‘Load any overlay’ loads NIFTI file or statistical parametric map (products of SPM8). ‚Add coordinate‘ ‚Clear coordinate‘ and ‚Clear all coordinates‘ set list of coordinates where it is necessary to check the validity of loaded data. Coordinates are in [mm] in MNI space. Names of unsuitable files are displayed in list ‘Unsuitable masks’. Coordinates ‘Point coordinate [voxel]’ are coordinates of voxel of background image, targeted by crosshair.
