I have just uploaded Biome-BGCMuSo v4.0.7 [source code and Windows exe] to the website of the model: http://nimbus.elte.hu/bbgc/download.html
If you used previous version of Biome-BGCMuSo v4, please replace the executable with the new one. Some bugs were corrected, so this is the latest and [hopefully] final release of v4. The new model version will be implemented in the BBGCDB website.
Don't hesitate to contact us if you have questions.
Cheers,
Zoltan BARCZA and Dora HIDY
