我们在前面曾讲到R语言如何读取SDF文件，今天给大家介绍下，读取后如何获取分子的相关信息。Chemistry Development Kit (CDK)数据资源是一个主要获取化学分子属性信息的JAVA库。其官方主页：https://cdk.github.io/。
同时其提供了相对应的JAVA接口供各用户使用。今天就给大家介绍下在R语言中是如何利用其接口进行相应的化合物数据获取的。
首先，我们看下需要安装的包:
install.packages('rcdk')
接下来我们直接通过实例来看下此包的使用：
1. 数据的输入与输出
##数据载入Dir1=system.file("molfiles","kegg.sdf", package = "rcdk")Dir2=system.file("molfiles","dhfr00008.sdf", package = "rcdk")mols 
当单个分子sdf文件太大时，我们为了防止内存溢出，那么我们可以遍历读取：
##遍历读取数据iter type=while(iter$hasNext()) { mol$nextElem()set.property(mol, 'cdk:Title', 'A')print(get.property(mol,"cdk:Title"))}
##单个分子的解析读取，当然也可以直接读取多个分子smile 'c1ccccc1CC(=O)C(N)CC1CCCCOC1'mol 1]]get.smiles(mol)# get.smiles(mols[[1]])
##多个SMILE结构数据的读取options("java.parameters"=c("-Xmx4000m"))library(rcdk)for (smile in smiles) {    m   ## perform operations on this molecule     .jcall("java/lang/System","V","gc")   gc()}
##分子的输出，如果参数together=FALSE，则挨个输出分子到sdf文件write.molecules(mols,filename='mymols.sdf')
2. 分子结构的获取
##SMILE转化为2D坐标m 'CCC')[[m 2d.coordinates(m)
##分子信息：绝对立体配置、增强立体功能、原子标签、波动键索引、环状立体键信息和反应片段级分组信息输出get.smiles(m,smiles.flavors(c('CxSmiles')))
##SMILE坐标信息获取get.smiles(m,smiles.flavors(c('CxCoordinates')))
3. 分子结构的可视化
###坐标系中添加分子结构img 2d(parse.smiles(plot(1:10, 1:10, pch=19)rasterImage(img, 1,6, 5,10)
4. 分子构造的解析
##原子骨架的获取mol 'c1ccccc1C(Cl)(Br)c1ccccc1')[[atoms get.atoms(mol)bonds get.bonds(mol)cat('No. of atoms =', length(atoms), '\n')
5. 分子描述信息(此包的核心部分)
##列举此包可获取的分子描述信息属性，包括了拓扑，构造，几何，电子和混合形式。dc 
##获取单个描述的具体信息名称dn <- get.desc.names(dc[4])
###计算描述中的各属性值aDesc <- eval.desc(mol, dn[4])allDescs <- eval.desc(mol, dn)
##获取所有描述属性的集合descNames <-unique(unlist(sapply(get.desc.categories(), get.desc.names)))
###通过描述信息集合获取对应的分子属性data(bpdata)mols 1])descNames  'org.openscience.cdk.qsar.descriptors.molecular.KierHallSmartsDescriptor', 'org.openscience.cdk.qsar.descriptors.molecular.APolDescriptor', 'org.openscience.cdk.qsar.descriptors.molecular.HBondDonorCountDescriptor')descs eval.desc(mols, descNames)
得到上面的矩阵，那么我们就可以进行下面的建模型，分析了。此包也给出了两个例子，我们直接看下：
1. 线性回归模型的构建
###数据清洗descs 2,descs descs[, !r2 which(r2 r2[ descs descs[, -
###构建模型model ~ khs.sCH3 + khs.sF +apol + nHBDsummary(model)
##可视化模型预测结果plot(bpdata$BP, predict(model, descs),    xlab="Observed BP", ylab="Predicted BP",    pch=19, xlim=c(100, 700), ylim=c(100, 700))abline(0,1, col='red')
2. 基于分子指纹的分层聚类分析，首先看下分子指纹的类型：
##获取分子指纹，此处类型为circulardata(bpdata)mols fps type=
##计算距离矩阵fp.sim 'tanimoto')fp.dist 1 - fp.sim
##可视化结果cls as.dist(fp.dist))plot(cls, main='A Clustering of the BPdataset', labels=FALSE)
当然，分子指纹还有另外一个功能，那就是分子检索，通过指纹的相似的进行分子的检索，我们直接看下实例：
query.mol 'CC(=O)')[[target.mols 1])query.fp get.fingerprint(query.mol,target.fps get.fingerprint, sims do.call(rbind,lapply(target.fps,    fingerprint::distance,    fp2=query.fp, method='tanimoto')))subset(sims, sim >= 0.3)
欢迎大家学习交流！

Java 窗体的使用，获取鼠标右键点击的坐标，其中使用了匿名内部类

import java.awt.FlowLayout;
import java.awt.event.MouseAdapter;
import java.awt.event.MouseEvent;

import javax.swing.JFrame;
import javax.swing.JLabel;

@SuppressWarnings("serial")
public class PositionOfMouse extends JFrame{
    private JLabel label;
    public PositionOfMouse(){
        super("测试程序");//建立新窗体
        this.setSize(400,300);//设置窗体的宽和高
        this.setVisible(true);//设置窗体可见
        this.setLayout(new FlowLayout(FlowLayout.CENTER));//框架流布局且居中对齐
        this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//设置点击关闭按钮时的默认操作
        JLabel label = new JLabel("此处显示鼠标右键点击的坐标");
        this.add(label); // 将标签放入窗体

        this.addMouseListener(new MouseAdapter(){  //匿名内部类，鼠标事件
            public void mouseClicked(MouseEvent e){   //鼠标完成点击事件
                if(e.getButton() == MouseEvent.BUTTON3){ //e.getButton就会返回点鼠标的那个键，左键还是右健，3代表右键
                    int x = e.getX();  //得到鼠标x坐标
                    int y = e.getY();  //得到鼠标y坐标
                    String banner = "鼠标当前点击位置的坐标是" + x + "," + y;
                    label.setText(banner);  //修改标签内容
                }
            }
        });
    }
    public static void main(String[] args) {
        // TODO 自动生成的方法存根
        new PositionOfMouse();
    }
