E-Prime® Extensions for fMRI Overview
E-Prime® Extensions for fMRI (EEfMRI) software is designed to optimize E-Prime® experiments for fMRI research. EEfMRI allows you to synchronize the start of your experiment with the first scanner trigger pulse along with several valuable features to enhance the control you have over your experiment. Implementing EEfMRI into your current experiments is achieved by simply dragging and dropping the correct EEfMRI package calls into the E-Prime® experiment in the appropriate places. EEfMRI is designed to integrate with other PST hardware and software to increase usability for researchers while maintaining the millisecond accuracy of E-Prime®.
E-Prime® Extensions for fMRI™ is intended for research use only.
E-Prime® Extensions for fMRI Features
- Synchronization of the start of the experiment with the scanner trigger pulse
- Simplified logging of user-specified experimental events to tailor behavioral output for later analysis
- Easy to implement menu system that allows the experimenter to group multiple tasks into a single experiment and interactively choose which tasks to present at run time
- Ability to interrupt a running task in a controlled manner to restart tasks without terminating the entire experiment
- New documentation including samples and tutorials
- Turnkey fMRI block sample (MapperOne.es2) based on a published experiment* that reliably activates important functional areas

E-Prime® Extensions for fMRI Requirements
- E-Prime 2.0 (Professional Recommended)
- Additional hardware for scanner trigger pulse synchronization with start of experiment
E-Prime® Extensions for fMRI FAQs
Q: Is there any additional hardware that I’ll need to synchronize my E-Prime experiments with the first scanner trigger pulse?
A: You will require any of a number of devices that can communicate via a TTL pulse to the experiment PC. PST includes this functionality with our Fiber Optic Button Response System (FOBRS).
Q: What sort of a connection do you have to have between the scanner and control room PC to enable the scanner-dependent software triggers to work?
A: This will depend on the model and age of scanner and what type of hardware you are interfacing with. Most new scanners have a fiber optic connection coming off of the scanner. For more information contact your scanner manufacturer.
Q: Will E-Prime Extensions for fMRI (EEfMRI) work with hardware from other manufacturers?
A: Yes, you can configure your EEfMRI enabled E-Prime experiment to work with third party hardware by making a few modifications to your experiment settings. For specific instructions, please contact web support.

Q: How does EEfMRI relate to BEST?
A: EEfMRI was formerly called BEST. If you have a BEST paradigm, you can convert it to EEfMRI using the application on our webpage.

Q: Can I use E-Prime Extensions for fMRI with any version of E-Prime?
A: E-Prime Extensions for fMRI is only compatible with E-Prime 2.0.
Q: Is there a specific manual for the package?
A: Yes, the documentation is included in your installation of EEfMRI, or you may download the EEfMRI Users Manual here.
Q: Is it easy to convert my current experiments to implement EEfMRI?
A: Incorporating EEfMRI support into an existing E-Prime experiment primarily involves adding both the EEfMRI Package File and the EEfMRI PackageCalls to the experimental structure at the appropriate locations. PackageCalls are added to the experiment, renamed and edited to set the required parameters, allowing the user to adapt EEfMRI to meet their individual needs.
PackageCalls are pre-written, cohesive sets of E-Basic routines grouped together in a single file that can be maintained externally. These libraries are included in the EEfMRI installation.
Q: Is it possible to start my experiment manually once I’ve enabled EEfMRI package calls?
A: Yes, to manually trigger your experiment all you will need to do is press the key that has been assigned to trigger the experiment (E-Prime sees the input as a key press).
E-Prime® Extensions for fMRI Support
E-Prime support is provided through the E-Prime Web Support site. Registration is required to gain access to the E-Prime Web Support site. The E-Prime Web Support site provides the latest updates, Knowledge Base section, Samples, Downloads, and a personal support forum to communicate with PST support representatives. Additional FAQs are also provided in the E-Prime product pages.
Click here to gain access to the E-Prime Web Support site.
Users are also encouraged to use the PST User Forum (a free service provided by PST for end users) to share information about any of PST's products.
In addition, an independent discussion list has been set up for E-Prime users (http://groups.google.com/group/e-prime/). Although this service is not run or moderated by PST, we wanted to inform you of its existence. We encourage you to participate in either or both forums as a means to share information about E-Prime and obtain assistance from a growing and experienced group of E-Prime users.
An archive of past discussions is maintained by Anthony Aristar's Linguist List system http://listserv.linguistlist.org/archives/eprime.html.
