Hi @christoph-hue, Z scoring of the microarray data has already been address in [this community forum post](https://community.brain-map.org/t/transcriptomics-rna-seq-microarray-data-normalization-faq/182). Can you take a look at that and reply to this thread if it does not address your issue? I don’t know how to calculate Z scores in the mouse ISH data so if that ends up being necessary, someone else will need to reply.
