PlexUtil 4.0 Enables Conversion from PLX Files to PL2™ Files
June 27, 2013

DALLAS, TX — (June 27, 2013) – Plexon Inc, the leader in advanced hardware and software solutions for neuroscience and behavioral research, releases PlexUtil 4.0 as an important component of the new, game-changing PL2™ file format launch. PlexUtil 4.0 will enable researchers to convert their PLX files into PL2 files, accessing the ability to load large neural data files faster than ever.

Historically, Plexon’s OmniPlex® Neural Data Acquisition Systems (the OmniPlex and OmniPlex D Systems) and the original Multichannel Acquisition Processor (MAP) Data Acquisition System have recorded neural data in the widely used, industry-standard PLX format. PlexUtil is Plexon’s file utility program that permits the manipulation of those files such as creating subsets of data and merging data.

In an announcement earlier today, Plexon launched its new PL2 file format, enabling the loading of large, high-resolution data files faster than ever before. Depending on the file characteristics, data loading can be 10, 100 or even 1,000 times faster. The newest release of the OmniPlex Software, v1.9, will allow researchers to record new files using the PL2 format in addition to the original PLX format. However, there are many research laboratories with large data previously recorded in the PLX format that will want to convert their files, leveraging its very practical benefits. PlexUtil 4.0 is now available to facilitate that conversion..

Researchers wishing to convert PLX to PL2 files will first need to do the following:

  • Download PlexUtil 4.0 from the Plexon website at, and
  • Ensure that their OmniPlex and/or MAP System license keys have been upgraded (at no charge) to unlock access to the PL2 conversion functionality.

Upgrading the license keys is a simple process. Researches should email with their OmniPlex and/or MAP System license key serial numbers (found on the back of the key following the “SN:”) and request the PL2 upgrade codes. Plexon will reply with the codes and further instructions. With the upgraded license key and PlexUtil 4.0 running on the computer, researchers will be ready to convert files.

More information regarding the PL2 format is available online in the PL2 File System Overview. Both the latest PlexUtil software and the PL2 upgrades to the OmniPlex and/or MAP System license keys are free of charge. For more information, visit or email
