      As per the RNASeq version 2 pipeline in the link below, I have been able to obtain outputs till step 11, i.e the transcriptome_alignments_filtered.bam output. Next step is to run rsem.



      I ran RSEM using the following command : /opt/rsem-1.1.13/rsem-calculate-expression --paired-end --bam --estimate-rspd -p 8 transcriptome_alignments_filtered.bam /home/group_sh/TCGA+SRA_datamergerquantification_RNASeqV2/RSEM_ref_from_TCGA_webshare/hg19_M_rCRS_ref ERR519523.rsem > rsem.log_2 > rsem.log

      I get this error in the log file :

      rsem-parse-alignments failed! Please check if you provide correct parameters/options for the pipeline!

      What is wrong? I donot understand. I am running exactly the same command!!!

      Kindly help.

        Are you using a different version of RSEM than the one in the PDF?

          No. I am using the same version mentioned in the UNC mRNASeq version2 document.

                Write directly to the contacts included in the TCGA doc with a request for help.
