Data Formats and Software

We currently run OPUS 8.0 at the IRM beamline for data collection and processing on both the online microscope and the offline FPA microscope. Data is routinely saved via OPUS in either of two Bruker OPUS file formats. Single spectra are saved as OPUS Spectrum files. 2D IR map files are saved as Opus Multiple files (.map). OPUS Multiple files contain all spectral and x-y spatial information for a two dimensional grid map, plus related captured video images. Opus 8.0 is compatible with data collected in older OPUS versions such as 6.5 and 7.2.

Data compatibility

Opus spectrum files collected in previous versions of OPUS can be read by the current Bruker Opus software (OPUS 8, recommended for data analysis), CAMO The Unscrambler v 9.8+ and by Thermo Grams /AI, all of which are available at the beamline for off-line data analysis.

OPUS Multiple files (.map) can be read by Bruker Opus 3D software and by CytoSpec v1.3, again which are available at the beamline for off-line data analysis.

Data conversion

Bruker spectrum files can be batch converted into the following file formats:

  • X-Y table (data point table – Excel compatible)
  • SPC format (Thermo Grams AI compatible

Users can access our onsite computers for post-beamtime data processing and analysis, either in the data processing section of the IRM cabin, or in our computer lab.

Analysis software

In addition to the latest version of Bruker Opus 3D, the following data analysis packages are available for use on the off-line data analysis PCs.

  • CytoSpec v 1.3.02
  • Thermo Grams AI (single PC licence)
  • The Unscrambler v 10.3

Offsite Access to Data for download or post-processing of data

At the completion of your beamtime, you will be sent an email with a link that allows you to access and download your data from the Australian Synchrotron SFTP service.  Follow the link and log in with you portal email address and password.  Once logged in, you can access a list of folders relating to each experiment you have attended.  You can download your data from here to your own local folder.  You will also receive a link with instructions on the secure file transfer protocol.

At the end of this email, you will also find a link to ownCloud to download a time limited version of OPUS 8.0, for analysing your spectral data.
