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!

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

Error using y_ExtractROISignal (line 239)

Hell0,
I have 3 groups of subjects, and I am using a ROIList.mat file for all 3 groups. It works without issues for 2 groups. For the third, it gives below error. What does it mean?-
