One of iolite’s key capabilities is its ability to model processes occurring with a measurement session as time series. This is achieved via a series of interpolation methods, collectively referred to here as “splines” although they range from a simple mean of the observed data through to variably smoothed cubic splines.

One handy feature that was slipped into iolite a while ago without much publicity is the ability to visualize “ImageLog” images in the time series view.

In iolite 3, sessions were saved as Igor Pro “packed experiment” pxp files. This was convenient because iolite 3 was built on top of Igor Pro.
