(I) Running bismark_genome_preparation USAGE:bismark_genome_preparation [options] <path_to_genome_folder>

A typical genome indexing could look like this:

/bismark/bismark_genome_preparation --path_to_bowtie /usr/local/bowtie/ -- verbose /data/genomes/homo_sapiens/GRCh37/



COMMAND

./bismark_genome_preparation --path_to_bowtie /Volumes/Bay3/Software/bowtie/ --verbose ./genomes


#note only single fasta placed in genomes folder.


--


# created these files




# next step

(II) Running bismark

USAGE: bismark [options] <genome_folder> {-1 <mates1> -2 <mates2> |

<singles>}

Typical alignment example (tolerating one non-bisulfite mismatch per read):

bismark -n 1 -l 50 /data/genomes/homo_sapiens/GRCh37/ test_dataset.fastq

February 06, 2012

This will produce two output files:

(a) test_dataset.fastq_bismark.sam (contains all alignments plus methylation call strings)

(b) test_dataset.fastq_bismark_mapping_report.txt (contains alignment and methylation summary)

NOTE: In order to work properly the current working directory must contain the sequence files to be analysed.



COMMAND
./bismark -n 1 -l 50 ./genomes/ /Volumes/Bay3/Software/bismark_v0.6.4/filtered_P_Ab_CO2_ACTTGA_L001_R1_trimmed.fastq



#



#confirmed duplicate IDs, using Galaxy to resolve.

RESOLVED
NOW HAVE TO START OVER!!!!!!

Trouble shooting
trying bsSeqref

Trouble shooting
running test data

#win




appears to be problem with reads
going to try to give unique IDs


re importing and sending to Galaxy
00
re import should be faster
-next day
now need to trim and export

Exported to Scratch Drive, now ready to try Bismark again
