EPI distortion correction: COPE plugin

Cope user interface screenshot

EPI images suffer from geometric distortions due to non-zero off-resonance fields. The Cope plugin estimates and corrects these deformations using a pair of EPI images acquired with opposite phase-encoding directions (either anterior-posterior and posterior-anterior, or left-right and right-left).

If you don't have the current version of COPE installed, download the ZIP file for your operating system below, unpack it, and place the files in your BrainVoyager plugins folder (e.g., User\Documents\BVExtensions\Plugins_64). You can then start COPE from BrainVoyager's Plugins menu and access the manual by going to Plugins > Description Of Plugins and scrolling down to the section for COPE.

The manual can also be found online here

Note 12-11-18: Please note that in the plugin is stated that the order of file submission does not matter; however, it turns out that for some datasets, it is better to upload A>>P as the first file and P>>A as the second file (instead of P>>A first). We will also test this for the file submission order of L>>R and R>>L.
