HTS (NGS) 関連のインフォマティクス情報についてまとめています。




  • electrophoresis sequencing(別名サンガーシーケンシング
  • イルミナ(Solexa)シーケンシング
  • あまりない。454パイロシークエンシング(GS20、FLX、Titanium)
  • 少ない: イオントレント


MIRAはMimicking Intelligent Read Assemblyの頭文字を取ったもので、このプログラムはその頭文字通りの働きをする。このプログラムは、著者自身が過去20年間に使用・開発してきたシーケンスアセンブリのスイスアーミーナイフであり、自身が担当するアセンブリ作業を効率的に、そして特に正確に行うためのものである。

mira [options] manifest_file [manifest_file ...]



  -c / --cwd= directory Change working directory

  -m / --mcheck Only check the manifest file, then exit.

  -M / --mdcheck Like -m, but also check existence of

data files.

  -r / --resume Resume an interrupted assembly

  -h / --help Print short help and exit

  -m / --mcheck Only check the manifest file, then exit.

  -M / --mdcheck Like -m, but also check existence of

data files.

  -r / --resume Resume/restart an interrupted assembly

  -t / --threads= integer Force number of threads (overrides

equivalent -GE:not manifest entry)

  -v / --version Print version and exit

# Example for a manifest describing a de-novo assembly with
# unpaired 454, paired-end Illumina, a mate-pair Illumina
# and a paired Ion Torrent

# First part: defining some basic things
# In this example, we just give a name to the assembly
# and tell MIRA it should assemble a genome de-novo in accurate mode
# As special parameter, we want to use 4 passes with kmer sizes of
# 17, 31, 63 and 127 nucleotides. Obviously, read lengths of the
# libraries should be greater than 127 bp.
# Note: usually MIRA will choose sensible options for number of
# passes and kmer sizes to be used by itself.

job = genome,denovo,accurate
parameters = -AS:kms=17,31,63,127

# The second part defines the sequencing data MIRA should load and assemble
# The data is logically divided into "readgroups": this reflects the
# ... that read sequences ...

# defining the shotgun (i.e. unpaired) 454 reads
