GANKO Software Distribution (GSD)

What is the GSD?

The GSD provides computer programs and datum produced in our lab as results from research activities.


Before you download a program or data, you need to accept our license term. The `license term' consists of (1) the general license term and (2) an individual license term provided with each program or data. If a program or data has both terms, you should accept both terms. If an individual term conflicts with general term, an individual term is valid. If a program or data does not have its own individual term, only the general term is valid.

Please read the general license term.
