Added new function of "corr(i1,i2,'spatial')" in REST Image Calculator. (DONG Zhang-Ye)

Dear Dr. Dong

I notice a new function added into REST Image Calculator, "corr(i1,i2,'spatial')" .

What is the 'spatial' correlation between image 1 and image2?

Is there any ref. about this  'spatial' correlation?

Thanks.

REST-GCA paper mistake in formula wrriten.

A wrriten mistake in transformation of F values to F' values in REST-GCA paper was pointed out by Mr. WU Guorong. We thank Mr. Wu for the correction and we confirmed the REST-GCA toolkit code is correct.
We apologize to readers for this mistake. In the readme file of REST-GCA, this formula is correctly presented. Users could download the readme file in REST-GCA section.

MRI有明确病变的被试可以用DPARSF进行分析吗

 老师您好:

       我发现大部分针对静息态的研究被试都是常规MRI没有明确病灶的,那么对于常规MRI能够发现病变的能否运用DPARSF软件进行分析,或者说能否进行静息态脑功能研究呢?谢谢!

这种情况应该用multiple regression 还是one-way ANOVA between subjects

大家好,有个问题请教下:
      我在试验中收集有午睡习惯的被试每周的午睡天数,有4 5 6 7共四个选项,如果我想找到午睡习惯可能影响到的脑区(使用VBM数据),应该是使用multiple regression 还是one-way ANOVA between subjects哪?如果使用one-way ANOVA between subjects的话,contrast vector应该怎么设置才能满足我的目标那?
      谢谢!

REST slice viewer的模板匹配合理性的问题

各位老师:

troubles while processing DPARSF basic edition, never happened before

Dear REST experts:

Recently I run the DPARSF basic edition and I faced the following wrong messages in my matlab command window

??? Error using ==> spm_slice_vol at 32
spm_slice_vol.c not compiled - see Makefile

Error in ==> spm_slice_timing at 213
slices(:,:,m) = spm_slice_vol(Vin(m),B,Vin(1).dim(1:2),1);

DPARSF滤波报错

严老师,

normalize the subject's mask to MNI space

Dear Dr. Yan,

I have used the DPARSFA (Caculate in MNI space warped by DARTEL) to prepocess my data. All of the preprocessed data were in MNI space now.

请教一下张寒老师有关mica中成分挑选sort components和identify components的使用方法

我在使用mica的时候,在成分挑选的时候,gui view界面中点击sort components,并且选择空间相关并加载了需要的DMN网络模板,点击ok之后,软件没有任何反应,
问题1:恳请张寒老师指导一下,mica中sort components的使用。
问题2:identify components在使用默认的设置,全部勾选,点击ok,matlaB就会报错,请问identify components的作用以及他的使用方法。
Idendentify components
??? Undefined function or variable 'dim'.

Connectivity Matrices

     老师您好,想请教下,在运用NBS CONNECTOME这个软件时,用DPARSF作后处理, AAL模板, 如何获得Connectivity Matrices? 我看 NBS CONNECTOME软件的说明书中提到可以用DPARSF产生的.多谢指教!
