IDEOM version 18 now available

[Darren Creek]

Hi IDEOM users, 

A new version of IDEOM is available online for download. 

http://sourceforge.net/projects/mzmatch/files/Ideom/ 

This version includes many minor bug fixes for different types of data, plus: 

- An import function to transfer old IDEOM files to a new version (to allow you to apply the latest functions to older data without repeating all the processing and curation).   Look in the TOOLS menu on the settings sheet.

- The 'Filter peakML' function has been upgraded (available in the R script menu on the Settings sheet) to allow you to filter a peakML file according to a list of peakID's (for example by identified metabolites). 

- The Rank Products calculation now gives more accurate FDR values for large sample sizes. ** Note: if using this function on large datasets please verify results from another tool, particularly if using IDEOM versions before v18. 

- Numerous improvements to GCMS processing. Scores are now provided for spectral matching where spectra are available within IDEOM (Note: included spectra have not been manually verified at this stage). Individual features can now be searched directly against the online Golm Metabolite Database by double-click in column C. 

- An extra field in the settings sheet (F44) allows you to allocate multiple cores for faster peak processing in XCMS

- Numerous cosmetic and functional improvements. Thanks to Gavin Blackburn for the function to keep chromatograms visible when a cell in column A is selected. 

Enjoy!
