Software for scientific data analysis.


Past is free software for scientific data analysis, with functions for data manipulation, plotting, univariate and multivariate statistics, ecological analysis, time series and spatial analysis, morphometrics and stratigraphy.

Simple yet powerful scientific data analysis solution

The Past user interface is represented by a single window where you can visualize the imported data. Note that Past can extract information from text files, and you get to decide how it should be organized.

Moreover, Past also enables you to remove the rows or columns that contain irrelevant information, to add new ones, or to simply reorganize the information.

Via the app’s top toolbar you can choose to see the row or columns attributes, to change the selection mode, to activate the bands function and see the rows better, and more.
