I need some suggestion about the mark duplicates command using picard tool, can anyone tell me if in the input and out label we can specify path as well or not? as I want to run 6 samples together so I will use it as a script and execute all of them one by one so can I specify path in the input and out like below.
java -Xmx14g -jar /data/PGP/gmelloni/picard-tools-1.84/picard-tools-1.84/MarkDuplicates.jar INPUT=/test/exome/input/SRR062634.sorted.bam OUTPUT=/test/exome/results/SRR062634_marked.sorted.bam REMOVE_DUPLICATES=False METRICS_FILE=metricN.log ASSUME_SORTED=True VALIDATION_STRINGENCY=LENIENT

I am doing RNA-seq data analysis. I am still not very sure it is neccessary to remove the duplication or not.

I'm having trouble with this MarkDuplicates. I hope someone could help. When I didn't include the "VALIDATION_STRINGENCY=LENIENT" I got an error saying "Mate Alignment start should be !=0 because reference name != *". But when I included it there's these error line that keeps changing extremely but its running. Is this normal?

When I used picard to remove dulications, I used fastqc to check. It still have a high duplication level (63%). Why?

Hi,
I usually increase the RAM used, change the validation stringency and define a tmp dir.
My example will look like this:
java -Xmx4g -jar ~/bin/picard/MarkDuplicates.jar INPUT=accepted_hits.bam OUTPUT=remove_accepted_hits.bam METRICS_FILE=dup.txt VALIDATION_STRINGENCY=LENIENT REMOVE_DUPLICATES=true TMP_DIR=/tmp

example for using Picard removing duplicate reads?
Does anybody can give me such example?
java -jar ~/bin/picard/MarkDuplicates.jar REMOVE_DUPLICATES=true METRICS_FILE=dup.txt INPUT=accepted_hits.bam OUTPUT=remove_accepted_hits.bam
Thank you very much.Tags: None

The complexity of cancer is clearly demonstrated in the diverse ecosystem of the tumor microenvironment (TME). The TME is made up of numerous cell types and its development begins with the changes that happen during oncogenesis. “Genomic mutations, copy number changes, epigenetic alterations, and alternative gene expression occur to varying degrees within the affected tumor cells,” explained Andrea O’Hara, Ph.D., Strategic Technical Specialist at Azenta. “As...-
