博客主要讲述ITK出现‘there are no registration IO factories’异常的原因，即ITK无法识别要读写的文件格式。读取时内部读者无法接受文件、写入时文件名扩展名不被识别都会引发。还给出解决方法，如在CMake配置中启用IO模块，添加特定头文件和注册工厂等。

问题：exception message ：there are no registration IO factories

原因：

This exception is thrown when ITK does not recognize the fileformat that you are trying to read or write. When reading, ITK recognize file formats by asking a set of internal readers to attempt to read your file. If none of the registered readers accept your file, then the exception above is thrown. When writing, ITK uses the extension of the filename in order to chose the fileformat to be used. Make sure that you use one of the filename extensions recognized by ITK, and that the ImageIO class for that format has been registered.

Enable all the IO modules that you wish to support in your ITK CMake configuration.

解决方法：和读取image file类似的处理方法

1、添加头文件：#include "itkTxtTransformIOFactory.h"

2、添加：itk::TxtTransformIOFactory::RegisterOneFactory();

注意：

保存transform的文件格式不同，添加的头文件不同：HDF5TransformIO, MatlabTransformIO
