MDA-MB-231 Morphology Training and Test Sets

Text file format contains measurements from binary images of training and test set examples of five cancer cell migration modes observed in MDA-MB-231 cells in 3D migration. Class 0 = actin-enriched leading edge. Class 1 = Filopodia. Class 2 = Hemi-spherical blebbing. Class 3 = Lamellipodia. Class 4 = Small-bleb. Please note, classes 2 and 4 are both bleb-based migration mechanisms and do not display significant separation in shape-space. Therefore, these classes can be combined during training to describe migration dominated by contractility.Line 1 contains geometric measure titles, with the last column being the class each example is part of. Each other line is a training example. Each measure units are in micron scale, if appropriate. Binary images of training and test examples are available upon request.Raw images from subset of training images have been uploaded as well (all .png files).本数据集的文本文件包含针对三维迁移环境下MDA-MB-231细胞的五种癌细胞迁移模式的训练集与测试集样本的二值图像所提取的几何测量数据。各分类的定义如下：类别0为富含肌动蛋白的前沿（actin-enriched leading edge），类别1为丝状伪足（Filopodia），类别2为半球形泡状伪足（Hemi-spherical blebbing），类别3为片状伪足（Lamellipodia），类别4为小泡状伪足（Small-bleb）。需注意，类别2与类别4均属于基于泡状结构的迁移机制，二者在形状空间中无显著区分度，因此训练阶段可将这两类合并，以表征以细胞收缩力为主的迁移模式。文本文件首行列出各项几何测量指标的名称，最后一列标注每个样本所属的类别。除首行外，其余各行均对应一个训练样本。所有测量指标的尺度单位均为微米（若适用）。训练集与测试集的二值图像可按需申请获取。部分训练图像的原始.png格式原图也已一并上传。
