sc2_SimmulatedValidation_ClinAnnotations.csv file includes following four studies: "DFCI", "GSE15695", "Hose", "M2Gen". I have two questions: 1) Are these studies all studies available for validation in sub challenge 2, or are there more studies (e.g. UAMS?)? 2) For "DFCI", "GSE15695", "Hose" datasets there is information [here](https://www.synapse.org/#!Synapse:syn6187098/wiki/449443). But I could not find any information (e.g. files location or platform) for "M2Gen" dataset.

Hi, The UAMS validation dataset does not have any expression data so there are just 4 cohorts you mentioned available for validation in challenge question 2. Also there is more information on the datasets [here](https://www.synapse.org/#!Synapse:syn6187098/wiki/449432) that you may find helpful.
