各位新老学员：

大家好！

美德医疗在大家的支持和鼓励下，不断推出新的培训课程，尤其在多次举办功能磁共振专项培训中积累了很多经验，为各学科人才在科研工作中提供学习和交流新技术的机会，得到了业内人士的高度肯定，相信大家学有所成，近几年也取得了非凡的成就。

在多方征集专家和学员的需求和建议后，经过精心策划和组织，我们即将在秋季推出全新的fMRI课程设计和别开生面的交流形式，旨在让学员们除了学习了解fMRI前沿新技术之外，也请多位在科研领域成功的讲师现身说法，以各自已发表的文章为例证，详细阐述他们从科研创想--思路形成--科研团队组织--科研方法探求--数据采集--数据分析--文章撰写--文章发表等科研全过程的成功经验，供大家学习讨论。

New Bug Report -regarding reslice timing

Submitted by wujingxi on Wed, 09/07/2011 - 10:39

各位好：
今日用DPARSF中的步骤处理task数据（滤波以前所有步骤），数据扫描的时候TR=2.

在处理数据的时候，软件自动报出‘Your TR is 1.8'。同一批数据，还出现了‘Your TR is 1.9'的情况，但是用mricro查看dicom转换为hdr/img的参数，仍然显示TR=2。

请问这是什么情况？
