一个基于QT的解析interproscan结果的C++成员函数

标签：qt   c++   interproscan   

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();
