MarkDuplicates error for RNA-Seq

Question

[KG]

Hi, I am trying to run MarkDuplicates but keep getting the error listed below, although I added the TMP_DIR=yourdirectory/tmp in command line.

Please advice Thanks a bunch!

**Command**
 *java -jar MarkDuplicates.jar INPUT= Read_sorted.bam OUTPUT=Read_sortremove.bam METRICS_FILE=metrics.txt REMOVE_DUPLICATES=true VALIDATION_STRINGENCY=LENIENT TMP_DIR=yourdirectory/tmp*


**Error**

Normally there is no need to mark/remove duplicates in RNAseq data.

Picard is not finding the temporary directory:

Exception in thread "main" htsjdk.samtools.SAMException: /home/as/SNPiR/yourdirectory/tmp/CSPI.1714605993024191960.tmp/13316.tmpnot found

But listen to genomax suggestion, probably there is no need to mark/remove duplicates in your data.
