here you can modify analysis  settings for a selected  study folder. It requires a valid selected study folder, because all modifications will be saved in the "anslabdef.m"-file at the top-level of the study folder.

batch plotting (mat):

Create plots for all your data files to identify outliers and artefactual data. The procedure is described in detail on the subject- and sample-plot page.

batch plotting (ans):

Create plots for all your evoked data epochs to identify outliers and artefactual data. The procedure is described in detail on the subject- and sample-plot page.

timing file modifcation:

Use this command to modify existing timing files by specifiying a modification term for each line (interval) or each condition (trigger value) in the timing files. This tool can help you create smaller subsegments, collapse segments or modify segments by adding constant offsets. To start the modifcation process, first load a filematrix containing the paths of the timing files you wish to modify. Then select the timing file modification item from the tools menu. You are prompted to  select a definition file, that specifies how each line is to changed. Allowed commands in the definition file are

subdivide n;
subdivfixed n m;
collapse start;
collapse end;
collapse;
leave;
drop;
offset;
setlength n;
add [n, m];
fromonset [n, m];

A sample definition file for line based modification could look like this:

A sample definition file for condition based modification has an additional (tab delimited) column before each definition specifying for which trigger values the definition is applied. It could look like this:

timing file recoding:

Use this command to modify the condition numbers in existing timing files by specifiying a replacement list. Every condition number in every file is then replaced according to the replacement list. To start the modifcation process, first load a filematrix containing the paths of the timing files you wish to modify. Then select the timing file recoding item from the tools menu. You are prompted to  select a text file, that specifies how the replacements are to be made. This file must be a two column tab-delimited  text file, the first column containing the original condition number, the second column the value which will replace the original. A sample definition file can be found in the 'anslabutil'-folder in the ' timing'-subfolder, and it's content is shown here:

import IBI data:

Import raw IBI data recorded e.g., from Polar watch or Actiheart devices. Load a batch file specifying the file locations of the raw IBI files.
A one-column text file of raw IBI data is needed for each recording:

855.00
790.00
763.00
765.00
781.00
748.00
...

A folder to place the imported files can be selected. The sampling accuracy for the imported IBIs is assumed to be 1000 Hz. All values will be rounded to full milliseconds.
A *.mat file will be created for each imported file which has the structure of a an edited ecg file. This can be used for further analysis (e.g., spectral analysis or value export). The IBI raw data can also be loaded into the ecg analysis module for manual editing of outliers. For this, the following settings are needed:
