Question about wAutomask

Dear all,

                Recently, I met some problems when I  used Dpabi for fMRI data preprocessing .

                1) Usually,after normalization,  error "Function 'subsindex' is not defined for values of class 'matlab.ui.Figure'." will be reported in matlab so that we couln't obtain PicturesForChkNormalization files. Our version of matlab is 2017b in Ubuntu 16.04, how do we work out this problem? Or what's recommend version  of matlab?

QA: ROI outlines/functional & structural

Dear DPABI users

Would it possible to generate a QA report for ROI outlines overlay on the top of functional & strcutral images in MNI space?

Thanks for considering my request.

Best wishes

Two Post-doc Positions in Lisbon, Portugal

Two Post-Doc positions opened at the Biomedical Neuroscience Lab (https://dpratalab.wordpress.com/; PI: Dr Diana Prata, with double affiliation in King’s College London), at the University of Lisbon - for research in human social neuroscience and the oxytocin and the dopamine systems in a highly interdisciplinary 3-year project involving pharmacology, genetics and a range of psychophysiological techniques.

Error in timepoints for preprocessed data in DPARSF V2.1

Dear Expert,

I am running rs-fMRI demo data provided on your website for 3 subjects on DPARSF V2.1  for ALFF and ReHo calculation. I preprocessed data till smoothing on SPM12 running on Matlab R2016a. After preprocessing I put all the data in FunImgNormalizedSmoothed folder. For detrending and filtering when I use DPARSF V2.1, I am getting an error for timepoints (screenshot attached). 

Any help would be appreciated.

Happy New Year 2019!

Dear Researchers at The R-fMRI Network,

Happy New Year 2019!

Thank you very much for spending another year with us, let’s welcome an exciting new year of 2019!

dataset

你好,我目前在做脑图像配准,我想要ADHD和ABIDE原始数据集去除颅骨后的大脑部分数据集,而不是经过你们提取的灰质,白质部分。不知道能不能进行共享一下。我在ADHD的数据集上通过fsl软件,做了去颅骨,但是大脑部分和颅骨还是有一些粘连,颅骨去除的效果不好。因此想从你们这拿到去颅骨的数据集。万分感谢!

TDA information

Dear Prof. Yan,

The TDA module was performed to calculate the concordance (the dynamic metrics was calculated before, e.g. the alff+falff, reho, DC and GSCorr ) and the error information was as follows,

Calculating Functional Connectivity by Seed based Correlation Anlyasis finished, elapsed time: 23.6406 seconds.

DPABI output- ROIsignals.text differences

Dear Experts,
I re-ran 2 subjects through DPABI using the same parameters and ROIs that I used for the same two people that I ran as part of a larger group ( n=50).
When I compare the output folders FunImgARCFWS_ROISIGNALS/ROISIGNALS_subjectx of the same person, the ROI time courses look very different, even though I used the same parameters as before.
Would you know why that is? I can only imaging that in my prior analysis these two subjects were run as part of a different group? Does the ROISignals .text output gets normalized according to the included subjects?

error when use Permutation test

严老师好,

我这用dpabi做FC与行为学的相关的时候出现了如下报错,应该如何处理?

我使用的dpabi版本是V3.1, MATLAB2017,WINDOWS 系统。

 

ANOVA报错与Mask问题

1. 使用Dpabi中的统计分析进行ANOVA分析比较三组的FC差异
事后比较选择Tukey检定,正常的F.nii可以正常生成,但是事后比较出现付图的报错
后来有试着运行其他事后比较,Tukey和雪费都会报错但是Dunnet和Bonferroni可以运行,请问是下列报错是哪些地方操作错误了呢?
2.教学影片中有提到如果欲使用AlphaSim或是GRF等校正,需要选取MASK档案,但是我不知道这个Mask档案应该在哪个目录下,Masks目录下的AllresampledBrainMask没有任何内容又是正常的吗?
感谢老师的答覆
