错误提示显示不全，建议将全部错误信息复制后粘贴在帖子中。前期数据转换是否正确？

如何春传给您前期数据

Caoyufu · March 4, 2019, 1:38am

貌似b值不对，转换出错或者原始数据缺少参数，发我原始数据，邮箱地址：444703546@qq.com

cc0514504 · March 4, 2019, 1:59am

好的谢谢曹老师，数据已经传过去了

Caoyufu · March 4, 2019, 2:23am

Mask brain失败原因是数据转换出错。

首先应用mango看看哪个是需要的数据？

通过show file菜单得知SE8为需要的数据。

成功转换到3DSlicer中

mask brain成功

更详细的转换方法参见3DSlicer社区公众号教程。

如下图所示，数据需要配准后才能多模态融合显示。

cc0514504 · March 4, 2019, 2:59am

谢谢曹老师，我抓紧时间实践一下
最后那张图是其他的数据？真漂亮

曹老师，我们最初几步到底是用DWI数据还是DTI数据

Caoyufu · March 6, 2019, 9:19am

是用1352个文件的DTI序列，最后的图片就是你的数据做出来的。

老师您好！能把原始数据给我也发一份吗？我最近也在做这个，我的邮箱是：warfarin2020@163.com，谢谢您！！！

从3DSlicer获取数据的方法：

1、示例文件获取：Sample Data

2、从Data Store获取
