HEM/SCS

From Waisman Brain Imaging Wiki

The HEM and SCS computers were once used at Brogden to collect EEG and general physiological data. The SCS computer was the equivalent of EPrime, and the HEM computer was the equvalent of BioSemi or BIOPAC. The HEM/SCS system was quite good for its day, and was very flexible, but it is now quite outdated, and suffers from serious noise problems, is quite difficult to configure and debug, has hundreds of fragile and unmarked wires hanging out from patch panels right next to the researchers' chairs, and can only collect 32 channels of EEG plus a few general channels.

Most older studies at Brogden were collected using the HEM/SCS computers, and were originally stored and processed on the old VMS servers. Much of the data has been converted to a more modern format and transferred to the UNIX servers, but some of it may still be stored on old VMS optical disks and tapes. If you need to reanalyze data from a very old study, you might need to talk to Aaron about the location of the data and if it will need some TLC before you can even look at it.
