If you have any questions about this release, please feel free to email us at support@iolite-software.com

Version 4.0.9

A big update that adds a lot of new features (see below) and addresses a few issues

• Added a new 'Channel Calculator': you can create new channels by entering an expression. For example, if you want to create a new channel with the U/Th ratio, the expression would be U238_ppm / Th232_ppm. Click calculate and as easy as that, you now have a new channel. It'll even let you know if your expression worked. Check it out in the Tools menu -> Calculator. We'll add a blog post describing it in detail soon.
• You can now export 'selection marker' files. These files allow you to save a group of selections so that, for example, you can re-run processing templates etc and then reload manually.
• You can now save your export configurations to file. You can then share these files with others, so that your colleagues are using the same export format/options etc.
• Added more statistical details (e.g. MSWD)to the Results views, as well as fixing problems with values not updating in this view.
• After a lot of work, we have introduced support for Perkin Elmer .rep files. There are many variations on this file format, so if you have troubles, please get in contact with us.

A quick update to address the following issues:

• Now each time you add a channel to the Time Series View, it has a new color
• You can now replace values less than the LOD with -[LOD]. For example, if your value was 1 µg.g-1 and your LOD was 2 µg.g-1, it will be replaced with -2 in the export file by using -[LOD] in the export options.

Version 4.0.1

In this update, we have fixed an import issue that affects timestamps with lowercase am/pm. We have also added the ability to use Regular Expressions when searching for files or samples in the Data Browser (see this wikipedia entry for details on Regular Expressions).

We have also fixed an issue where the Processing Templates view did not update after the lanuage was changed.

If you have any questions about this release, please feel free to email us at support@iolite-software.com
