Tasknames
Creating a taskname is one of the simplest way to link behavioral files to a functional dataset, and ideal for scans that have a single comparison (such as activity versus rest). Tasknames are files that label a specific task protocol run in the scanner(such as Language). Another file may be created with the same taskname that contains all the relevant behavioral data, as well as are a set timing description. Several different tasknames can be created, each with a different timing reference and behavioral data, and they can be used on fscan to quickly generate activation maps of functional images. If a taskname file has been created, simply open the Stats taskbar, select autotask, and an activation map of that dataset will appear.
In order to verify which taskname is being used by autotask, go to the File taskbar, select the 'show data set header' icon, and this will open a header window with all the information about the data set, including the taskname used. To switch the taskname, open the command line, type
- -set taskname (yourtaskname)
This will switch the task file being used in the dataset. To run an automatic ttest, go to the Stats taskbar again and select autotask.
To create a new taskname to run, open a text window and type in a timing reference (Ex: -r timing1 timing2 delay 4.5 -ttest 1 2) and save it as yourtaskname.fscan. This will automatically pull up the file when run with autotask.
