- Velvet 安裝紀錄(2009-11-11)
- 測試 Velvet 1.1.03 (支援 OpenMP)
- 系統:Debian Squeeze
~$ sudo apt-get update; sudo apt-get upgrade; sudo apt-get dist-upgrade ~$ sudo apt-get install build-essential ~$ wget http://www.ebi.ac.uk/~zerbino/velvet/velvet_1.1.03.tgz ~$ tar zxvf velvet_1.1.03.tgz ~$ cd velvet_1.1.03 ~/velvet_1.1.03$ make ~/velvet_1.1.03$ ./velveth output 17 -fasta -short data/test_long.fa ~/velvet_1.1.03$ ./velvetg output/ -exp_cov 3 -min_contig_lgth 100
- 使用 valgrind 來進行記憶體分析
~/velvet_1.1.03$ sudo apt-get install valgrind ~/velvet_1.1.03$ valgrind --tool=massif ./velveth output 17 -fasta -short data/test_long.fa ~/velvet_1.1.03$ ms_print massif.out.10571 ~/velvet_1.1.03$ valgrind --tool=massif ./velvetg output/ -exp_cov 3 -min_contig_lgth 100 ~/velvet_1.1.03$ ms_print massif.out.10561 ~/velvet_1.1.03$ valgrind -v --leak-check=full --show-reachable=yes --read-var-info=yes ./velveth output 17 -fasta -short data/test_long.fa 2> velveth.log ~/velvet_1.1.03$ valgrind -v --leak-check=full --show-reachable=yes --read-var-info=yes ./velvetg output/ -exp_cov 3 -min_contig_lgth 100 2> velvetg.log
- 使用 gprof 進行 profile 分析
~/velvet_1.1.03$ cat Makefile | sed "s#^CFLAG.*#CFLAGS = -Wall -pg#" > ~/velvet_1.1.03$ mv Makefile.new Makefile ~/velvet_1.1.03$ make ~/velvet_1.1.03$ ./velveth output 17 -fasta -short data/test_long.fa ~/velvet_1.1.03$ du -sh gmon.out 56K gmon.out ~/velvet_1.1.03$ ./velvetg output/ -exp_cov 3 -min_contig_lgth 100 ~/velvet_1.1.03$ du -sh gmon.out 152K gmon.out
- 使用 gprof2dot 把 gprof log 轉成 graphviz 的 dot 格式,就可以畫出圖形了。
~/velvet_1.1.03$ sudo apt-get install graphviz python ~/velvet_1.1.03$ wget http://gprof2dot.jrfonseca.googlecode.com/hg/gprof2dot.py ~/velvet_1.1.03$ chmod a+x gprof2dot.py ~/velvet_1.1.03$ gprof velveth | ./gprof2dot.py | dot -Tpng -o velveth.png ~/velvet_1.1.03$ gprof velvetg | ./gprof2dot.py | dot -Tpng -o velvetg.png
