A new stable release 1.9.0 is available from the download site. This release adds functionality to the LUA commands to import spectra into projects and allows spectra which are not found during loading of the repository to be ignored. See News and release notes for details.
A beta release of CARA 1.9.1b16 includes support for larger spectra (64 bit) and a new scope for analysis of 4D spectra. It also supports relative pathnames for spectra.
NEW LUA script CompareProjects.lua to compare the assignments in two projects and report differences (assigned in only one, signficant shift deviations)
Updated LUA script WriteSparkyPeakList.lua so it can write 2D, 3D, and 4D sparky peaklists.
