As mentioned in the CBI users meeting today, the firm deadline for the complete removal of the old projector system at 30 Bee St is March 1st, 2013, which is looming (since between Thanksgiving and New Years people tend to disappear). I will be sending out bi-weekly reminder e-mails for people to swap over. I have already talked with the all the groups that present visual stimuli during their MRI sessions, but in case you’ve forgotten, you NEED to modify your E-prime files if you’re in the following situations:
- You are currently running a study that will NOT end by March 1st, 2013.
- You are starting a new study with visual stimuli
For those studies that will be ending prior to March 1st, 2013, you don’t need to do anything to your E-prime files. Here are the modifications necessary to display properly on the new projector:
- If you would like your image files to actually fill up the screen, your image’s resolution must be AT LEAST 640 x 480. In some cases where original image files are very small, this may require replacing the images entirely. If the image cannot be replaced, then you can try upsampling the image using software like Adobe Photoshop, though your results will vary depending on the original resolution.
- You must also change the Eprime display resolution to at least 800 x 600. Here is a powerpoint pdf that details the specifics of the new projector setup. The last slide has instructions on changing the Eprime display resolution.
- Finally, I highly encourage anyone who is still using Eprime 1 files to convert to the Eprime 2 file format. This makes software support easier, and will also provide your programs with added functionality, should you choose to take advantage of it in the future. The process is very simple and painless, and is detailed here: http://www.pstnet.com/forum/Topic5016-2-1.aspx#bm5017
Note that when you convert this way, your original file will be untouched, and you will be prompted to save a new eprime2 file.
Since the projector removal deadline is March 1st, it would be good if everyone who is making significant changes to their Eprime programs (upsampling images, replacing images, testing movies, etc) to have built a new program and tested it at least once prior to Monday, January 14th. In case there are bugs, this still provides time for additional testing and tweaking.
