* **filetype**: files in the filetype will be searched in input directories.
* **data dir**: directory where :file:`\*.mat` result of NETWORK CALCULATION is stored.
* **stat type**: one sample t-test, two sample t-test and paired t-test.
* **groups**:
* for two sample t-test, e.g. SZ,NC -> will do two-sample t-test for SZ and NC
* for paired t-test, e.g. SZ,NC -> will do paired t-test for SZ and NC
* for one sample t-test, e.g. SZ;NC -> will do one-sample t-test for both SZ and NC group
* **grouping info**:
* **table**: A comma-seperated values (csv) table, which is used for parsing subject names and covariates. The parsed names/ids will be matched to search results conducted with datadir and filetype. Before matching, BRANT will remove specified strings.
* For one and two sample t-tests:
====== ======== ========== =======
name group filter age
====== ======== ========== =======
subj1 SZ center1 28
subj2 SZ center1 27
subj3 NC center1 30
subj4 NC center2 25
====== ======== ========== =======
* For paired t-test, another column of paired_t_idx is required to specify paired subjects in each group:
====== ======== ========== ======= =============
name group filter age paired_t_idx
====== ======== ========== ======= =============
subj1 stage1 center1 28 1
subj2 stage1 center1 27 2
subj3 stage2 center1 30 1
subj4 stage2 center2 25 2
====== ======== ========== ======= =============
* **string removal***: optional. remove partial string from string parsed by id index.
* **regressors***: optional. title of regressors which will be regressed out before statistical analysis. e.g. age
* **filter***: optional. use the control for subject in different state or center, fill in center1 here and subject4 won't be included in the analysis.
* **discard subjects without info**: when checked, if subjects' information are not found in the table, a warning message will be shown; when unchecked, an error message will be shown.
* **out dir**: output directory for saving results.
* If the output figure is empty, check whether there is NaN or Inf in the output :file:`\*.csv` files, where the raw global network properties are extracted.
- **Buttons**:
- **S**: Save parameters of the current panel to a :file:`\*.mat` file. The :file:`\*.mat` can be further loaded for the panel or be used in a script processing.
- **L**: Load parameters from :file:`\*.mat` for the current panel.
- **?**: Help information.
