Sep 2023: TOPPE has been almost completely rewritten to make it a more accurate interpreter of Pulseq files. Please see the Pulseq on GE manual for more information. To view a redacted version of that manual that contains minimal GE specific information, click this link. If your institution owns a GE MRI scanner you can obtain the unredacted version of the manual on gecares.com (look for a post by Jon-Fredrik Nielsen in the MR Software Sharing forum on gecares.com), or contact Jon-Fredrik Nielsen at jfnielse@umich.edu.

We now recommend that you design your sequence in Pulseq, and then convert the .seq file to a .tar file that can be run on a GE scanner with the TOPPE interpreter. The manual describes how to perform this conversion.

As a result, most of the information on this page is obsolete, and has been removed.

The interpreter (EPIC source code) is hosted in a separate repository – for access, fill out this Google form, or just send an email to jfnielse@umich.edu.
