nuisance regression error

Extracting ROI signals...Error using y_ExtractROISignal (line 239)
An UndefinedFunction error was thrown on the workers for 'MaskROILabel'.  This might be because the file
containing 'MaskROILabel' is not accessible on the workers.  Use addAttachedFiles(pool, files) to specify the
required files to be attached.  For more information see the documentation for 'parallel.Pool/addAttachedFiles'.

Issue about data preprocessing

I'm a rooky and want get help for a basic problem. 

There are many ways to process the data preprocessing, which makes me a bit confused. Please help me check if my process is correct.

For Reho, the sequence is Slice Timing-Realign-reorient Fun-filter-normalize by epi-nuisance covariates regression-reho-smooth reho.

For alff and falff, the sequence is Slice Timing-Realign-reorient Fun-smooth-normalize by epi-nuisance covariates regression-alff+falff.

Thanks!

關於差值的相關性

各位老師大家好!!

我的實驗中,有介入組別,而我想要去看說介入前後的心跳變化與介入前後變化的腦區 的相關性

我使用了correlation test 但是我卻無法一次加入兩組的data

我想請問各位老師,有沒有一個好方法去計算此兩個變化的相關性?

Normalization for ReHo analysis

Hi all,

About the spatial normalization for ReHo analysis, I wonder which one is better, T1 image unified segmentation or EPI template, for the spatial normalization of ReHo? Cause my findings show significant differences between T1 and EPI template. Since the ReHo-KCC algorithm computes the neighborhood voxels, it is intuitively that simple spatial transformation should not have resulted in distinct patterns.

In the same vein, what template (EPI-MNI vs T1-MNI) should be the most optimal one for seed-based and graph-based functional connectivity analyses? Thank you~~

PALM running error

Good afternoon, Dr. Yan.
 
I performed a two sample T-test with ALFF. PALM could run without covariate images. However, error occurred when PALM ran with covariate images. Statistic set and error report were shown in the pics. And there is no space in all paths.
 
I had try  the analysis on Matlab2014a in Windows as well as on Matlab2016b in Linux system. Both of them reported the same error. How to deal with this error?  
 
Look forward to your reply.

VMHC处理问题

严老师好,最近在处理VMHC的过程中遇到了几个问题,希望您能解惑:

1.是不是因为要制作组内T1对称的模板,所以必须所有数据一起处理?如果因为内存问题,我能不能分批次处理,那么要从具体功能核结构的哪个文件夹一起保留呢?同时还要保留哪些文件夹?

2.因为要用到对称T1模板,所以健康人和患者的数据是不是要分开处理?然后组间分析的时候制作mask是要用健康和患者的对称T1mask一起取并集么?
