Hello,everyone

I used Picardtools/MarkDuplicates as following:

    java -jar picard.jar \
    	INPUT=A01-2m-D6.sort.bam \
    	OUTPUT=A01-2m-D6.bam \
            METRICS_FILE=A01-2m-D6.metrics CREATE_INDEX=true 2>A01-2m-D6.picard_MarkDuplicates.stderr

then I met thus error:

    picard.sam.markduplicates.MarkDuplicates done. Elapsed time: 2.38 minutes.
    Runtime.totalMemory()=2058354688
    To get help, see http://broadinstitute.github.io/picard/index.html#GettingHelp
