version 4.5.1:
- changed variant calling tests in accordance with changes made to bam_tally in gmapR

version 4.4: 
- bioc release version bump

version 4.2: 
- bioc release version bump

version 4.1.15:
- investigating a memory fault produced by tallyVariants() in the test.callVariantsVariantTools.genotype() unit test

version: 4.1.13:
- fixing NGSPIPE-191: removed mergeReads and peared references ; changed BioC imports ; should build on the BioC server (but cannot
  right now due to VariantTools::tallyVariants memory issues)

version 4.1.11:
- fixed NGSPIPE-182: updated the documentation of generateSingleGeneDERs(), highlighting that
  the function generates DEXSeq-ready exons by disjoining the whole exon set, keeping only the exons of coding regions
  and keeping only the exons that belong to unique genes.

version 4.1.10:
- add simple check for duplicate ids to prepocessReads. Note this will only catch dups within a chunk.

version 4.1.9:
- fixed a small glitch that prevented truncateReads to work with trimReads.trim5 config parameter
  only (without length truncation)

version 4.1.8:
- fixed NGSPIPE-167: added 5'-read trimming with the configuration parameter trimReads.trim5
  (code, unit test, configuration check code, handling corner cases)

version 4.1.7:
- fixed the NGSPIPE-150 ticket: cleaned up readRNASeqEnds and removed consolidateByRead
  
version 4.1.6:
- fixed a buglet (absence of summary_alignment.tab file) that prevented test.callVariantsVariantTools.genotype()
  to run
- moved the loading of genomic_features in countGenomicFeatures and not countGenomicFeaturesChunk, for speedup
- R CMD check ok  

version 4.1.5:
- fixed the NGSPIPE-172 ticket on "variant calling slow on GRCH38". The selftest took about 1.5 h to complete,
  due to the analyzeVariants() phase of the two test.runPipeline.Exome() tests, each lasting about 0.6 h.
  This was due to (1) a wrong loading of the huge dbSNP database for avgNborCount filtering (needed only if
  the avgNborCount keyword is present in the config parameter "analyzeVariants.postFilters". And due to (2) a
  costly tiling of the genome, which is not required for small datasets (with a number of reads lower
  than 100e6). The selftest now takes about 34 minutes to complete.

version 4.1.4:
- added test.readRNASeqEnds.dupmark() to test if readRNASeqEnds() handles properly dups (which is the case; the 
  bug NGSPIPE-180 on "Ignore Dup marked reads during feature counting" is due to the fact that markdup is done
  on whole bams, while featuring counting is done on chunks). This revision closes NGSPIPE-180.

version 4.1.3:
- filter out alignments that are marked as dups and QC failed using the proper bam flag before feature counting and coverage

version 4.1.2:
- activate read quality trimming for GATK-rescaled
- move sanger quality at the end of the list of possible qualities, as we do not do quality trimming for real sanger.
  Current and Recent data from illuma should always come with illumina 1.5 or 1.8 range, so we want to make
  sure the read triming is triggered.

version 4.1.1:
 - createTmpDir() is now more robust and retries if dir already exists. 
   this is needed as the indel realigner step uses this function to parallelize by chromosomes.
   For genomes with lots of chromomes/contigs such as GRCh38 (>200) this fixed a rare bug.

version 4.1.0: 
- starting new dev cycle

version 3.17.9:
- add variant_effect_predictor step

version 3.17.8:
- make sure chunk_dir points to some non-existant dir

version 3.17.7:
- VT changed its default Filters, probably due to an error.
  Until that is resolved, we manually create out Filterset ourselves.

version 3.17.6:
- de-activate indel Realignment step in mergeLanes again.
  Doesn't work as expected as chunk_firs are set to <merged> in config which throws up
  indel realignment step.

version 3.17.5:
- update buildGenomicFeaturesFromTxdb with GNE internal version
- add tests

version 3.17.4:

- disable genome tiling during bam_tallying, as it incures a huge time overhead 
  under some circumstances

version 3.13.18:
- new convenience function findVariantFile
- use genome tiling with VariantTools to keep memory footprint small

version 3.13.17:
- depend on VariantTools 1.6.1 to get the bamtally memory leak fix

version 3.13.16:
- version bump to match HTSeqGenie.gne

version 3.13.14:
- turn off read_min_length check in mergeLanes as due to qual trimming we now expect lanes to differ

version 3.13.13:
- speed up coverage step for WGS data by switching back to SimpleIntegerList if the coverage becomes too ragged.

version 3.13.12:
- repurpose the gatk.params config value, for general GATK params. This param will be passed on to all
  GATK calls. An example would be
  gatk.params:  -L intervals.bed
  to restrict realignment and variant calling to a certain subset of the genome thus saving 
  huge amounts of time for targeted sequencing approaches with a few hundred genes.

version 3.13.12:
- now uses TP53Which() (instead of which.rds) for variant calling tests
- now builds in BioC

version 3.13.11:
- now use TxDb.Hsapiens.UCSC.hg19.knownGene's version number in the TP53 genomic feature cache file, to avoid
  bugs when updating TxDb.Hsapiens.UCSC.hg19.knownGene

version 3.13.10:
- added an optional which config to limit VariantTools variant calling to certain regions

version 3.13.9:
- NA

version 3.13.8:

version 3.13.7
- enable indelRealigner in runPipeline controlled by
config value of alignReads.do

version 3.13.6
- set gatk.path in options if GATK_PATH env is set to an existing file.
This is mostly for allowing the unit tests to know if and where a GATK is installed

version 3.13.5:
- require bamtally bugfixed version of gmapR

version 3.13.4:
- fixed bug in generateCountFeaturesPlots() when no genes left after filtering.
  Practically only happens for bacterial or viral genomes when every gene is hit more than 200 times 

version 3.13.3:
- now saving fragmentLength in summary_coverage.txt
- using Jinfeng's weighted mean to estimate fragmentLength
- removed the parallelization in saveCoverage (since saveCoverage is used in parallel)

version 3.13.2
- activate read trimming for illumina 1.5 quality using the 'B' as qual indicator

version 3.13.1
- deactived the unit tests (test.wrap.callVariants, test.wrap.callVariants.parallel, test.wrap.callVariants.rmsk_dbsnp)
  until VariantAnnotation is fixed, to be able to compile HTSeqGenie on BioC servers

version 3.11.8
-choice of VT filters configurable via config

version 3.11.7
- mergeBams(..., sort=FALSE) in alignReads.R: since bams are already sorted in chunks, merging preserves the order
  and no re-sorting should is necessary

version 3.11.6
- saveCoverage now outputs a summary.coverage summary file

version 3.11.5
- directly export coverage from Rle with rtracklayer::export (instead of to make a memory-costly convertsion to a RangedData object)

- use a maximum of 12 cores in preprocessReads

version 3.11.2
- trim lowest quality tail of reads according to Illumina manual.
  This new quality step precedes the regular quality filtering that is still done.

version 3.11.1
- allow to use better filters for variant tools
  by default, uses standard filters (bad),
  but if repeat masked track and dbsnp are given in config it uses those.

- overload logdebug, loginfo and logwarn with a try() statement, to prevent errors when 
  concurrent threads are logging at the same time

version 3.4
- change gsnap param -E from 4 to 1. This should allow gsnap to find more translocations.

version 3.3.11
- get rid of analysis type. At this point the only thing we do differently for Exome vs RNASeq
  is the call to gsnap. Since that is actually created from the snp, splice and gsnap_param option
