Hi @vbhave. I don’t think anyone has addressed the exact question you are referring to; however, for your more specific question of how to get gene expression values for all genes in a single anatomical region, [this has been addressed in another thread](https://community.brain-map.org/t/extracting-data-for-all-genes-from-an-roi/507/3) (which it seems you were also a part of!). If you do find that this type of normalization improves your analysis of the [Adult mouse brain atlas](http://mouse.brain-map.org/) data, please let us know (for example, by posting a link to your future publication in this thread).
