GATB的使用小例子test.cpp

本站寻求有缘人接手，详细了解请联系站长QQ1493399855

1.touch test.cpp,,文件夹中 出现test.cpp

touch test.cpp

2. test.cpp的内容

#include <gatb/gatb_core.hpp>int main (int argc, char* argv[]){// a small GATB exampleconst size_t span = KMER_SPAN(1);typedef Kmer<span>::ModelCanonical Model;Model model (5);Model::Kmer kmer = model.codeSeed ("AAGTC", Data::ASCII);std::cout << "revcomp kmer: " << model.toString(kmer.revcomp())    << std::endl;}

3.编译,显示结果

具体

To get started with your own code (let's say, test.cpp), here is a quick walkthrough

wget https://github.com/GATB/gatb-core/releases/download/v1.2.2/gatb-core-1.2.2-bin-Linux.tar.gz
tar xf gatb-core-1.2.2-bin-Linux.tar.gz
mv gatb-core-1.2.2-bin-Linux gatb-core

Create a small example code in test.cpp:

#include <gatb/gatb_core.hpp>
int main (int argc, char* argv[])
{// a small GATB example
​const size_t span = KMER_SPAN(1);typedef Kmer<span>::ModelCanonical Model;Model model (5);Model::Kmer kmer = model.codeSeed ("AAGTC", Data::ASCII);std::cout << "revcomp kmer: " << model.toString(kmer.revcomp())    << std::endl;
}

Now the folder structure looks like:

test.cpp
gatb-core/
gatb-core/include/
gatb-core/lib/
...

To compile:

g++ test.cpp -Igatb-core/include -Lgatb-core/lib -lgatbcore -lhdf5 -ldl -lz -lpthread  -std=c++0x -O3 -o test 

Then the program is ready to run:

./test

Output:

revcomp kmer: GACTT

========================================

使用它同样的方法

Here, we simply compile a snippet taken from the 'examples' directory: 将它 取出来

(二)debruijn1.cpp

g++ debruijn1.cpp -Igatb-core/include -Lgatb-core/lib -lgatbcore -lhdf5 -ldl -lz -lpthread  -std=c++0x -O3 -o debruijn1

./debruijn
