| Description | Software mask_explorer_2 is update of the release mask_explorer_1. New features of the update are: 1. Menu with functions in top of GUI window. 2. Importing and exporting coordinates (*.mat files). 3. Listbox with coordinates reacts on mouse right clicks and keyboard to interactively change selected coordinate as actual. 4. Batch mode for creating masks. 5. Report of suitable masks can be exported to xls or txt. 6. Compatibility with SPM12b, SPM12, Matlab R2013b and Matlab R2014b. This software is written to explore fMRI datasets and to find inconsistences in fMRI data. It 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 (originally in version 7.14.0.739 (R2012a)) and uses parts of toolbox SPM (originally SPM8 (version 4290)) Compatibility to newer versions of Matlab (2013b, 2014b) and SPM (12b and 12) was tested. User can on left side of GUI load data (Load masks or cons) from several subjects (NIFTI, ANALYZE). Loaded inputs are used to create parametric map. Its values show number of datasets with spatially valid information. This map (GSBC) and group mask (GCMS) can mask_explorer_2 save. 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. Mask_explorer_2 can export list of unsuitable masks to *.xls or *.txt files. |
