Most of the pileup functionality, +such as outputting mapping quality and read positions, have been added +`mpileup'. + +Since this release, `bcftools view' is able to perform contrast SNP calling +(option -T) for discovering de novo and/or somatic mutations between a pair of +samples or in a family trio. Potential mutations are scored by a log likelihood +ratio, which is very simple in math, but should be comparable to more +sophisticated methods. Note that getting the score is only the very first step. +A lot more need to be done to reduce systematical errors due to mapping and +reference errors and structural variations. + +Other notable changes in samtools: + + * Improved sorting order checking during indexing. + + * Improved region parsing. Colons in reference sequence names are parsed + properly. + + * Fixed an issue where mpileup does not apply BAQ for the first few reads when + a region is specified. + + * Fixed an issue where `faidx' does not work with FASTA files with long lines. + + * Bugfix: wrong SP genotype information in the BCF output. + +Other notable changes in bcftools: + + * Output the ML esitmate of the allele count. + + * Added the HWE plus F<0 filter to varFilter. For multiple samples, it + effectively filters false heterozygous calls around centromeres. + + * For association mapping, perform both 1-degree and 2-degree test. The + 2-degree test is conservative but more robust to HWE violation. + +(0.1.17: 6 July 2011, r973:277) + + + +Beta Release 0.1.16 (21 April, 2011) +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Notable changes in samtools: + + * Support the new SAM/BAM type `B' in the latest SAM spec v1.4. + + * When the output file of `samtools merge' exists, do not overwrite it unless + a new command-line option `-f' is applied. + + * Bugfix: BED support is not working when the input BED is not sorted. + + * Bugfix: some reads without coordinates but given on the reverse strand are + lost in merging. + +Notable changes in bcftools: + + * Code cleanup: separated max-likelihood inference and Bayesian inference. + + * Test Hardy-Weinberg equilibrium with a likelihood-ratio test. + + * Provided another association test P-value by likelihood-ratio test. + + * Use Brent's method to estimate the site allele frequency when EM converges + slowly. The resulting ML estimate of allele frequnecy is more accurate. + + * Added the `ldpair' command, which computes r^2 between SNP pairs given in + an input file. + +Also, the `pileup' command, which has been deprecated by `mpileup' since +version 0.1.10, will be dropped in the next release. The old `pileup' command +is substandard and causing a lot of confusion. + +(0.1.16: 21 April 2011, r963:234) + + + Beta Release 0.1.15 (10 April, 2011) ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
