Hi! Firstly, thank you for depositing data for this project! I am having trouble finding donor information that correlates with the barcodes in the processed files at syn16780177. I have downloaded the ROSMAP_Brain.snRNAseq_metadata_cells_20230420.csv file available but it did not have donor metadata. A file with barcode-donor mapping information and donor metadata (age, sex, etc) would be very helpful. Please let me know if I am missing something! Thank you for your time and help! Best, Valentina

Hi Victor, Could you please provide any suggestions as to how I can proceed? Thank you! Valentina
Hi Victor, Thank you for the response! I am using the processed files at syn21589957, which has cell IDs like MFC_B1_01_Cdx1_pAD0_ATCCACCTCTATCGCC. These IDs are not in the ROSMAP_snRNAseq_demultiplexed_ID_mapping.csv file. Could you please advise? Thank you, Valentina
Hi Valentina, Thank you for your question. Barcodes are mapped to individualIDs in [ROSMAP_snRNAseq_demultiplexed_ID_mapping.csv](https://www.synapse.org/#!Synapse:syn34572333). Donor metadata is in [ROSMAP_clinical.csv](https://www.synapse.org/#!Synapse:syn3191087). You may join these two files with whatever other file you are using to obtain the complete dataset. Please let me know if you have any other questions. Thank you, Victor
