  • Dictionary size problem in Picard HsMetrics

    Hi everyone,

    I'm following a Roche pipeline for the analysis of targeted bisulfite sequencing data and I'm in trouble with Picard CalculateHsMetrics.

    I create the indexed reference file with samtools faidx command and the indexed .bam with samtools index.

    When I run Picard, with the following command

    Code:
    java -Xmx4g -Xms4g -jar ~/bioTool/picard-tools-2.2.1/picard.jar CalculateHsMetrics BAIT_INTERVALS=DESIGN_bait_intervals.txt TARGET_INTERVALS=DESIGN_target_intervals.txt INPUT=2101435_S8_L001.clipped.bam.bai OUTPUT=2101435_S8_L001_picard_hs_metrics.txt METRIC_ACCUMULATION_LEVEL=ALL_READS REFERENCE_SEQUENCE=~/Data/MethylSeq/genomes/GRCh37_latest_genomic_idx.fa  VALIDATION_STRINGENCY=LENIENT TMP_DIR=.
    it terminates with the following exception:

    Code:
    Exception in thread "main" htsjdk.samtools.util.SequenceUtil$SequenceListsDifferException: Sequence dictionaries are not the same size (0, 297)
    	at htsjdk.samtools.util.SequenceUtil.assertSequenceListsEqual(SequenceUtil.java:188)
    	at htsjdk.samtools.util.SequenceUtil.assertSequenceDictionariesEqual(SequenceUtil.java:271)
    	at htsjdk.samtools.util.SequenceUtil.assertSequenceDictionariesEqual(SequenceUtil.java:257)
    	at picard.analysis.directed.CollectTargetedMetrics.doWork(CollectTargetedMetrics.java:114)
    	at picard.cmdline.CommandLineProgram.instanceMain(CommandLineProgram.java:209)
    	at picard.cmdline.PicardCommandLine.instanceMain(PicardCommandLine.java:95)
    	at picard.cmdline.PicardCommandLine.main(PicardCommandLine.java:105)
    It seems like there is a problem in the indexes, but I cannot figure it out.

    Solved,
    I was using indexed files (.bai and .fai) instead of proper files.

      Current Approaches to Protein Sequencing
      by seqadmin


      Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...

      Strategies for Sequencing Challenging Samples
      by seqadmin


      Despite advancements in sequencing platforms and related sample preparation technologies, certain sample types continue to present significant challenges that can compromise sequencing results. Pedro Echave, Senior Manager of the Global Business Segment at Revvity, explained that the success of a sequencing experiment ultimately depends on the amount and integrity of the nucleic acid template (RNA or DNA) obtained from a sample. “The better the quality of the nucleic acid isolated...
