Make sure you have decompressed your index file. Also, make sure you did not keep the compressed hsapiens_GCF_000001405_NCBI.idx.gzfile within the DATABASE folder after decompressing it as ExpressAnalyst assumes all files within the DATABASE folder to be an index file for your samples to be processed with. Kallipso tries to read the compressed file and somehow retrieves 7147020301611076383 as the index file version.
