SPM8数据分析中,neurological convention和radiological convention的问题

各位老师好:

我有一个spm8数据预处理的问题,想请教各位老师,还望不吝赐教。

我现在使用SPM8对fMRI数据进行数据预处理,是跟师兄学的处理方法,流程如下:从医院采集到radiological convention的数据;然后用MRIcro人为地对数据进行左右脑的flip,得到neurological convention的数据;然后把neurological convention数据导入spm8中,进行预处理。

可是最近,从网上的一些spm8的论坛里看到,说是spm8在处理数据的时候,会自动进行左右脑的flip,因此,只需要将医院采集得到的radiological convention数据直接导入spm8就可以了。如果真是这样,我以前分析的数据,左右脑岂不是都反了?

很希望各位老师能为我解惑。谢谢!

用dparsf处理reho时遇到了一个问题

大家好:
在用dparsf处理reho时遇到了一个问题(reho是先计算再做平滑),那么smooth是选还是不选(打勾么?),下面还有一个Data without smooth(这个我觉得应该打勾)
谢谢大家!

Indipendent Component Analysis: MULTICOMBI quality check

Hi, is there anyone who knows the ICA code MULTICOMBI of Prof. Petr Tichavsky? I am using it, but I am not sure I am able to evaluate correctly the accuracy of estimations.

horzcat error

Hello,

Having an error listed below when trying to do seed based resting FC. I ran the same options and used the same ROIs with another data set and had no errors so don't think it is my choice of ROIs. I am running DPARSF_V2.1_120101, SPM8, Matlab R2011b.

============
Error using horzcat
CAT arguments dimensions are not consistent.

Error in DPARSFA_run (line 1924)

Questions about the lateralization analysis

请教严老师两个问题:
1、怎么制作单侧的global mask?
2、REST与DPARSFA中的VMHC模块可以做灰质体积的VMHM吗?怎么做呢?
谢谢!

error when running fALFF preprocessing

I ran preprocessing without filter with no mask, but on the fALFF step I used the BrainMask_05_61x73x61.img after resampling it to one of my Detrended subject images.

Read 3D EPI functional images: "/home/kaitlin/data/univariate_masking/FunImgNormalizedSmoothedDetrended/spm_2012Sep28.ps".??? Undefined function or variable "VoxelSize".
