From 62a2e335bc1edb6b95cb2165b3032ea19842b9c1 Mon Sep 17 00:00:00 2001 From: Mauricio Carneiro Date: Thu, 15 Dec 2011 11:08:19 -0500 Subject: [PATCH 2/7] Changing HardClipper contract to allow UNMAPPED reads shifted the contract to functions that operate on reference based coordinates. The clipper should do the right thing with unmapped reads, but it needs more testing (Ryan is using it at the moment and says it works). Will write some unit tests. --- .../org/broadinstitute/sting/utils/clipreads/ClippingOp.java | 2 +- .../org/broadinstitute/sting/utils/clipreads/ReadClipper.java | 1 + 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/public/java/src/org/broadinstitute/sting/utils/clipreads/ClippingOp.java b/public/java/src/org/broadinstitute/sting/utils/clipreads/ClippingOp.java index 4a253b217..97855080c 100644 --- a/public/java/src/org/broadinstitute/sting/utils/clipreads/ClippingOp.java +++ b/public/java/src/org/broadinstitute/sting/utils/clipreads/ClippingOp.java @@ -247,7 +247,7 @@ public class ClippingOp { return newCigar;

This change and my previous change have dropped runtime when dynamically merging 2k BAM files from 72.6min/1M reads to 46.8sec/1M reads. Note that many of these changes are stopgaps -- the real problem is the way ReadWalkers interface with Picard, and I'll have to work with Tim&Co to produce a more maintainable patch. --- .../picard/sam/MergingSamRecordIterator.java | 247 ++++++ .../sf/picard/sam/SamFileHeaderMerger.java | 744 ++++++++++++++++++ .../gatk/datasources/reads/SAMDataSource.java | 34 +- 3 files changed, 1011 insertions(+), 14 deletions(-) create mode 100644 public/java/src/net/sf/picard/sam/MergingSamRecordIterator.java create mode 100644 public/java/src/net/sf/picard/sam/SamFileHeaderMerger.java diff --git a/public/java/src/net/sf/picard/sam/MergingSamRecordIterator.java b/public/java/src/net/sf/picard/sam/MergingSamRecordIterator.java new file mode 100644 index 000000000..4b1c7a999 --- /dev/null +++ b/public/java/src/net/sf/picard/sam/MergingSamRecordIterator.java @@ -0,0 +1,247 @@ +/* + * Copyright (c) 2011, The Broad Institute + * + * Permission is hereby granted, free of charge, to any person + * obtaining a copy of this software and associated documentation + * files (the "Software"), to deal in the Software without + * restriction, including without limitation the rights to use, + * copy, modify, merge, publish, distribute, sublicense, and/or sell + * copies of the Software, and to permit persons to whom the + * Software is furnished to do so, subject to the following + * conditions: + * + * The above copyright notice and this permission notice shall be + * included in all copies or substantial portions of the Software. + * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, + * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES + * OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND + * NONINFRINGEMENT.
