| (Thorfinn, april20 2012)
| |
|
| |
| ===Download===
| |
|
| |
| [[bambi.tar.gz]]
| |
| ===Usage===
| |
| Program is invoked with either:
| |
| <pre> | | <pre> |
| ./bammer view #samtools view/ single sample only | | samtools mpileup -b smallBam.filelist -f /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa |cut -f1-3 >small.sam |
| ./bammer uppile #This does emulates the samtools mpileup | |
| </pre> | | </pre> |
|
| |
|
| | | Use refFinder to find the bases for each position in '''small.sam''' |
| Inputfiles are supplied with either
| |
| <pre> | | <pre> |
| tmp.bam #single bamfile
| | cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa full >tst |
| -b bam.list #filelist containing bamfiles
| | cmp tst ../angsd/test/small.sam |
| -b bam.list -nInd INT #only select the first INT samples from bam.list
| |
| </pre> | | </pre> |
|
| |
|
| | possible options are |
| | ;inputIsZero |
| | ;full |
|
| |
|
| Regions of interest can be supplied by defining a region in the following way
| | These are flags, so examples are |
| <pre>
| |
| -r chr:a-b #select chromsome chr from a, to b
| |
| -r chr:-b #select chromosome chr from beginning to be
| |
| -r chr:b- #select chromosome chr from b to end of chromosome
| |
| </pre>
| |
|
| |
|
| If we want to dump different regions in the same run, this can be done with
| |
| <pre> | | <pre> |
| -rf regions.file #every region is on a newline, has same format as above | | cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa |head |
| | a |
| | g |
| | c |
| | t |
| | a |
| | c |
| | t |
| | c |
| | g |
| | g |
| </pre> | | </pre> |
|
| |
|
| | | Or if we want the chr position also |
| Program can also estimate genotypelikelihoods if uppile is selected
| |
|
| |
|
| <pre> | | <pre> |
| -GL 0 #SOAPsnp | | cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa full |head |
| -GL 1 #samtools
| | 1 13999902 a |
| -GL 2 #gatk
| | 1 13999903 g |
| | 1 13999904 c |
| | 1 13999905 t |
| | 1 13999906 a |
| | 1 13999907 c |
| | 1 13999908 t |
| | 1 13999909 c |
| | 1 13999910 g |
| | 1 13999911 g |
| </pre> | | </pre> |
|
| |
|
| Output is hardcode dumped in glfs.glfs, these is a binary double file. Information for first site is the first 10*sizeof(double)*nInd bytes. This is the samtools ordering AA,AC,AG,...
| | Or if the positions are zero index as opposed to one indexed: |
|
| |
|
| Information about the position is dumped in mafs.mafs. This is NOT the MAF, but simply a 2 column file with chr tab.
| |
|
| |
|
| |
|
| |
| Below are some examples for running the program
| |
| <pre> | | <pre> |
| #view commands below
| | cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa full inputIsZero |head |

| ==Technics==
| |
| Program spawns a single thread, when a chunk has been read, and the thread is not finished it will wait.
| |
|
| |
|
| |
| ==ieatgor==
| |
|
| |
| Extract lines from file in "gor" format. The files can be found in this [[ieatgor/][folder]]
| |
|
| |
| to compile
| |
| <pre>
| |
| g++ -O3 -o ieatgor ieatgor.cpp -lz
| |
| </pre>
| |
|
| |
| The target file must be sorted. example of target file
| |
| <pre>
| |
| chr1:22323:232322
| |
| chr10:10000:10000000
| |
| chr3:10000:10000000
| |
| </pre>
| |
|
| |
| A "gor" file is a file with the first coloum being the chromosome and the second coloum being the positions. The rest of the coloums are not important. The gor file must be sorted based on the positions and chr. gz gor files are also accepted.
| |
| example of a gor file
| |
| <pre>

| |
|
| |
| ==getliner==
| |
| NB HUGE BUG, must +1 when using -l and zipped files. Sorry for inconveincace. (tsk)
| |
|
| |
|
| |
| This is a general tool for extract lines from newline seperated textfiles (can be gz compressed). Getliners4 allows for complement grep, use '-v 1'. Default is '-v 0'. Program can also print out basic statistics for hit/nonhit if -i filename is supplied. getliners6.cpp tokinzes on \r, so should work on windows files.
| |
|
| |
| Download here [[getliners6.cpp]] .
| |
| <pre>
| |
| g++ getliners5.cpp -lz -O3 -o getliners
| |
| </pre>
| |
|
| |
|
| |
|
| |
| Program can either extract specific lines, or "keys". The linenumbers to extract must be 1-indexed (first line i 1). When using keys, you must supply which column to 'grep' for. The program builds an associative array of the keys. And therefore only a single pass of the datafile is required.
| |
|
| |
|
| |
| Fields in the datafile can be seperated by a delimiter that can be specified at runtine with the "-d " argument. Default is space/tab. If delimter is an escape sequence it will not work and the code should be modified.
| |
|
| |
|
| |
|
| |
| ==calcABBABABA==
| |
|
| |
| This is program that calculates ABBA-BABA related stats for a given chromosome.
| |
|
| |
| It can be downloaded here [[abbababatest.cpp]] and can be compiled with:
| |
| <pre>
| |
| g++ -O3 abbababatest.cpp -o calcABBABABA -lz
| |
| </pre>
| |
| To get all options just type
| |
| <pre>
| |
| ./calcABBABABA
| |
| </pre>
| |
| An example run cmd
| |
| <pre>
| |
| ../calcABBABABA -file /space/genomes/refgenomes/ancestal/hg19/shortForm/chr20.ans -bam testbamfilelistbotoV2chr20.txt -outfileprefix testbotoV2Chr20plus1x2 -blocksz 5
| |
| </pre>
| |
| The program outputs three files: an abbababa file (with only abbababa stats), a count file (with overall counts for the chromosome) and a summary file where the compile time, run time and the cmds and the input files used when the program was run are all listed.

Small fast cprogram to extract bases from a fasta file. Download here [1]

Example
Generate samtools chr pos ref doing
samtools mpileup -b smallBam.filelist -f /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa |cut -f1-3 >small.sam
Use refFinder to find the bases for each position in small.sam
cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa full >tst
cmp tst ../angsd/test/small.sam
possible options are
- inputIsZero
- full
These are flags, so examples are
cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa |head
a
g
c
t
a
c
t
c
g
g
Or if we want the chr position also
cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa full |head
1 13999902 a
1 13999903 g
1 13999904 c
1 13999905 t
1 13999906 a
1 13999907 c
1 13999908 t
1 13999909 c
1 13999910 g
1 13999911 g
Or if the positions are zero index as opposed to one indexed:
cut -f1-2 ../angsd/test/small.sam |./refFinder /space/genomes/refgenomes/hg19/merged/hg19NoChr.fa full inputIsZero |head
1 13999902 g
