We introduce a computer program for time series tuning and analysis.
Source code is available here: https://doi.org/10.5281/zenodo.10892346.
The well known in paleo-climatic community program AnalySeries after Paillard et al. is restricted to the Mac OS (32-bit) and no longer compatible with current versions of Macintosh OS. QAnalySeries is an attempt to re-implement the major functionality of AnalySeries thus providing the community with a useful tool. QAnalySeries is written using Qt SDK as a free software and can be run on Macintosh, Windows and Linux systems.

Data, target, time model must be a text two columns file with delimiters (space, tab, ",", ";" ). First column must be depth or time in increasing order. Adding and deleting of tie points are the same as in original AnalySeries with "Shift" and "Alt" buttons ("Shift-Alt-LeftButtonClick" to delete a tie on Ubuntu).
An experimental new version of QAnalySeries is now also available for testing at https://paloz.marum.de/QAnalySeriesWASM/index.html.
This version runs inside the user's browser, and is generated as a Webassembly "Web-App".
Limitation on mobile devices
Note that this version does not yet implement touch-screen gestures, and thus it is not currently possible to pinch-zoom. On Desktop machines a mouse-wheel allows horizontal zooming (or full zooming when additionally the Shift key is pressed).
This version includes an initial version of a Spectral Analysis function (under the Tools→Spectral Analysis Menu).
Data can be uploaded and downloaded to the local computer. Astronomical data can be downloaded on demand.

current version: v1.5.0
v. 1.5.0 of QAS is available: Fixed bug with opening of Project file;
Import data from csv multi-column tables with automatic recognition of headers in the first line.
"...Data, target, time model must be read from a text multi-columns ‘csv’ file with delimiters (space, tab, ",", ";" ). First line can be column headers (delimited variable names without spaces inside), the program will automatically recognise them as non numerical values. Select X (Depth/Age) and Y (Value) columns with drop-down lists. X column must be in increasing order...."

current version: v1.5.1
A little bug fixed and titles added in “Save data with ages” dialog;
A little bug in “Integrated insolation” is fixed. Does not make sense for tuning but for absolute insolation values in short interval time (see “Palinsol” R library)

QAS_152_mac_notarized is the first version that is a Universal (x86_64, arm64) binary.
