一个基于QT的解析interproscan结果的C++成员函数

结构域预测软件interproscan提供多种输出格式，出于后期分析的需要，选用了gff3格式。我比较喜欢结合数据库进行分析，所以先要把数据导入数据库。

我之前用QT写好了界面，所以只要在菜单里添加一个QAction、再在主窗口类中添加槽函数就可以了。这里给出我解析文件的槽函数。

void MainWindow::on_interproToMyDB(){    PfamToMyDBDlg * dbDlg = new PfamToMyDBDlg(this);    dbDlg->exec();    QFile qinFile(dbDlg->filename.toStdString().c_str());//    QFile qinFile("mypfam.gff3");    QStringList fullpath = dbDlg->filename.split(QRegExp("/"));    QString path;    for(int i = 0; i < fullpath.size() - 1; i++){        path.append(fullpath[i]);        path.append("/");    }//    QMessageBox::information(this, "ERROR2", path);    //QFile qoutFile( "a2.sql");    QFile qoutFile( path+dbDlg->name+".sql");//    QMessageBox::information(this, "ERROR3", dbDlg->filename.toStdString().c_str());//    QMessageBox::information(this, "ERROR4", dbDlg->name);    if (!qoutFile.open(QIODevice::ReadWrite | QIODevice::Text))    {        QMessageBox::information(this, "ERROR1", "failed to open");        return;    }    if(!qinFile.open(QIODevice::ReadOnly | QIODevice::Text))    {        QMessageBox::information(this, "ERROR2", "failed to open");        return ;    }    QTextStream myTextStream(&qoutFile);    while (!qinFile.atEnd())    {        QByteArray line = qinFile.readLine();        line[line.size()-1]='\0';        QString str(line);        if(str[0]=='#'||str.size() == 0)        {            continue;        }        if(!str.startsWith("WP_")){            break;        }        QStringList sections = str.split(QRegExp("\t"));        if(!sections[sections.size()-1].startsWith("Name")){            continue;        }        QStringList sections2 = sections[sections.size()-1].split(QRegExp(";"));        QStringList sections3 = sections2[2].split(QRegExp(" "));        QString SQL;        if(sections3.size() != 3 || sections2.size() != 6 ||\                !sections3[0].startsWith("Target=") || \                !sections2[0].startsWith("Name") ||\                !sections2[1].startsWith("signature_desc") ||\                !sections2[3].startsWith("status")||\                !sections2[4].startsWith("ID")||\                !sections2[5].startsWith("date")\                                         ){            QMessageBox::warning(this, "ERROR", QString("format is wrong here, please add manully:\n")+sections[sections.size()-1].toStdString().c_str());            continue;        }        SQL.sprintf("insert into res_smart(Name, signature_desc, Target,start , stop, status, ID_SEQ, date, Uid)values(\"%s\", \"%s\", '%s', '%s' , '%s', '%s', '%s', '%s',(select Id from project_abbr where name = '%s'));", \            sections2[0].split(QRegExp("="))[1].toStdString().c_str() ,\            sections2[1].split(QRegExp("="))[1].toStdString().c_str() ,\            sections3[0].split(QRegExp("="))[1].toStdString().c_str() ,\            sections3[1].toStdString().c_str() ,\            sections3[2].toStdString().c_str() ,\            sections2[3].split(QRegExp("="))[1].toStdString().c_str() ,\            sections2[4].split(QRegExp("="))[1].toStdString().c_str() ,\            sections2[5].split(QRegExp("="))[1].toStdString().c_str() ,\            dbDlg->name.toStdString().c_str());         myTextStream<<SQL<<'\n';    }    qoutFile.close();    qinFile.close();}

PfamToMyDBDlg继承自QDialog，也一并给出

要提取的部分不包括后面的序列。中间部分的特点是以换行符区分不同字段，所以如果不做复杂分析的话，可以将这部分结果直接拷贝到excel进行分析。
