Offline Sorter v3.3.1 with Expanded PL2 Functionality
August 07, 2013

DALLAS, TX — (August 7, 2013) – Plexon Inc, the leader in advanced hardware and software solutions for neuroscience and behavioral research, announces the newest release – version 3.3.1 – of the neuroscience industry’s most recognized and trusted offline neural spike sorting software, Offline Sorter™.

With more than 1,200 publications specifically citing its use, Offline Sorter is the ubiquitous program for sorting neural signals captured during scientific research. In addition to reading Plexon file types – PLX and the newest PL2™ – Offline Sorter reads file types from many third-party data acquisition companies and software programs across the industry. Plexon released the latest upgrade – Offline Sorter v3.3.1 – with added PL2 functionality among other improvements. PL2 is Plexon’s new game-changing neural data file format. Compared to its predecessor, PLX, the new PL2 format enables much faster read-times – 10, 100 or even 1000 times faster!

Offline Sorter v3.3.0 first recognized PL2 files and was released earlier this year. Now, its PL2-related functionality has been expanded. Most significantly, PL2 files that are read into Offline Sorter may now also be Exported in the PL2 format in addition to being Saved as a PL2 file. The Export function is typically used for files where spikes have been extracted from continuous data. It is important to note that neither PLX files nor non-Plexon file types can be saved as PL2 files in Offline Sorter. Rather, the conversion from one format to another must be performed using PlexUtil 4.0 with an OmniPlex® Neural Data Acquisition System or a Multichannel Acquisition Processor (MAP) Neurophysiology System license key.

One other improvement related to PLX files is that Offline Sorter v3.3.1 now sets the initial spike channel gain to be the same as continuous gain. This enhancement makes future spike extraction much easier.
