Three newly released toolboxes: ES Calc, TUMOR, Decom (all beta version), try and have fun!

Submitted by ZHANG_RESTadmin on Sat, 08/23/2014 - 22:44

I, on behalf of all contributors, would like to announce that three toolboxes are released for free downloading. All of them are Matlab-based, thus unzip and setpath is required (we encourage setpath SPM8, REST, DPARSF as well). For more details please see each toolbox's manual. These software are beta version v1.0, so please feel free to pose any comment, feedback, bug report, suggestions. We will make them better accordingly. I'd like to briefly state the usage of them:

1. ES Calc: Toolbox (effect_size.zip) as well as manual (English version and Chinese version).

DPABI中DICOM Sorter出错

Submitted by xiaopeng on Thu, 08/21/2014 - 10:17

之前用REST分类DICOM数据出错，提示ProtocolName出错，试着在REST_DicomSorter.m中分别改成SequenceDescription和SequenceName之后运行还是出错。
之后在DPABI->Utilities->DICOM Sorter做相应修改（改成SequenceName）后再运行，出现一下报错：

??? Index exceeds matrix dimensions.

Error in ==> w_DCMSort at 15
    fprintf('Read %s etc.\n', OneDICOM{1});

Error in ==> DPABI_DCMSORTER_TOOL>ComputeButton_Callback at 227
w_DCMSort(DICOMCells, HierarchyValue, AnonyFlag, OutputDir);

Error in ==> gui_mainfcn at 96
        feval(varargin{:});

AlphaSim矫正咨询

Submitted by Learner--ECNU on Wed, 08/20/2014 - 23:03

 各位老师好，我在使用SPM做双样本T检验的时候，explicit mask选用的是我的单样本T检验结果的并集MASK，这样的话最后双样本T检验的结果如果使用AlphaSim矫正的话，就不能直接使用REST slice viewer里面自带的那个表里的参数了吧？需要重新对我的并集MASK进行AlphaSim值进行评估，我想再问下如图中，在估计AlphaSim的时候这里的P值是什么意思？估计的时候需要改吗？

DPARSFA

Submitted by pritha on Wed, 08/20/2014 - 08:55

Hi,
I'm using demo data and DPARSFA. When I choose my working directory (which has two folders FunRaw and T1Img) it does not pick up participants. But when I run then it shows. Can you tell me what's going on? If I use basic edition of DPARSF it picks up correctly.
Thanks,
Pritha

DPARSF Advanced版本无法找到participants，手动添加也找不到，而basic能找到是怎么回事

Submitted by You.Jia on Fri, 08/15/2014 - 10:52

 各位专家，我想询问下为什么刚刚下载的DPARSF来处理ProcessingDemoData，进入Advanced版就无法读取participants右键添加也找不到，而basic版能自动找到，是怎么回事呢？
数据文件按视频说的存在了F/Analysis/FunRaw

overlay result images to check regional overlap among different analyses

Submitted by Jie123 on Wed, 08/13/2014 - 03:56

Dear experts,

I have finished running the Reho and fALFF in DPARSF. The brain regions that have significant group differences (patients vs healthy controls) seem overlap between Reho and fALFF. I would like to take a closer look at these results, but slice viewer can only have one overlay at a time. Is there any way/script that would help to overlay more than one statistical images on top of each other in Rest or Brainnet viewer?

thank you very much!

Jie

ALFF反映的是状态还是特质？

Submitted by Yangmei Luo on Sat, 08/09/2014 - 21:56

 各位老师好！
      我最近用ALFF与某个心理变量之间的关系进行了分析，得到了一些脑区的ALFF值与某个心理变量有关。有审稿专家说ALFF反映的是状态的变化，问得到的结果反映的到底是状态上的关系还是特质上的关系。所以，我想请教各位老师：ALFF真的只是反映了状态的变化吗？与特质有没有关系？先提前感谢您在忙碌之中的回答！

使用DPARSF做任务态fMRI图像预处理报错

Submitted by gingervirgo on Sun, 08/03/2014 - 15:10

各位老师，大家好！
想使用DPARSF做预处理，数据是4组，每组20人，每个人有2个run。我将每个人的每个run给予独立的命名，如sub_001_run1，sub_001_run2，整理存入FunRaw。再将每个人的3dT1相数据整理存入T1Raw文件夹下对应的sub_001_run1。复制一份存入sub_001_run2。由于是任务态的数据，我只想做realign，normalize by using segment T1 ，smooth。

DPARSF中我只选择了：EPI DICOM to NIFTI,Realign,Reorient Fun*,T1 DICOM to NIFTI,Affine Regularisation in Segmentation,Normalize,smooth
