You can now download the latest version of SpiSOP beta 2.3.1 and get started.

New version includes:

Bugfixes with the Browser function for scoring, export messages and help for shortcuts.

Additional result export for slow oscillation detection (negative up-to-downstate slope added, distinct from former down-to-upstate slope)

Improvement power(-density) estimation, the window function can now be adjusted to be broader (0 to 100%) and thus can take higher spectral resolution by discarding less data.
