SPANA for Spectral Data Analyses [Download] Copyright (c) 2010 ykuroda All right reserved.

   SPANA is supplied as the "zip" archive file. Since the file is not a self-extracting archive, the file is necessary to be manually extracted by using an appropriate archive tool.
　After extraction of the archive file, the setup of SPANA starts from double clicking on the "setup.exe" program and following the program's instructions. Since the set up procedure create no icon of SPANA on your desktop, you should make the necessary short cut icon from the "spana.exe" file (usually) in the "c:\Program Files (x86)\spana" folder and place it on an appropriate position. To start SPANA under Windows, double-click on the SPANA icon.
　In the "spana" folder, the simplified manual, sample data for "dat" and "tab" formats, the zip-archive file, "SampleData.zip" containing other sample data, and "ExternalPrograms.zip" containing samples of external programs are included.
For bugs or problems, please inform by e-mail.

a) See the program published at https://github.com/tvijverb/BEADS_Baseline_correction for the BEADS calculation algorithm. Also see https://qiita.com/skotaro/items/d943bc9a50da9410e9cb for an example of its use.
***************************************************************************************

The general non-linear least square program, LSPE, and the least square program for the reaction kinetics analyses, REDAP, are newly released. These programs are written in C language and run on the DOS box of WINDOWS.
LSPE allows nonlinear least-squares optimization calculations for data with multiple dependent variables, including multiple independent variables
For details, contact by e-mail (yasuhisa.krd@hotmail.co.jp)

　*Mar. 1, 2024, release improved LSPE
