DPABI/DPABISurf/DPARSF

Dear Experts,

I'm quite new to DPARSF and try to do an ALFF/fALFF analysis to feed the results into a paired statistical test (session difference).

I'd like to know what does the blue filter button do after the ALFF/fALFF radio button and band.

If I mark it, the filter part (5 lines above) becomes active and shows the band's lower and upper cutting points in blue.

i followed the instruction of Doc. yan_DPABISurf Installation on Windows | The R-fMRI Network (rfmri.org)

when i finally test the dpabisurf processing by running utilities as the instruction, matlab returns:

docker : invalid reference format. 

see "docker run --help"

besides, there is no report of error during the whole process of installation. 

can anyone help ?

thanks

各位老师好，

        我想请教几个做ICA之前数据预处理的问题：

       1. 我用DPARSF做预处理，除了slice timing, realign, normalize, smooth四步外，是否要做nuiscance covariates regression? 我查的资料看到有两种说法，一种是无需回归协变量因为ICA能够分离独立信号源无惧协变量影响；另一种说法是推荐在上面四步之外加一个Bias correction，但这个Bias correction是SPM做预处理的步骤，不知在DPARSF里面是否对应nuiscance regression?

Dear DPABI team,

first, I would like to thank you for your work and effort – I enjoy working with DPABI. I hope I didn't miss or overread information in this forum about the questions I'll ask in the following, if so I would like to apologize beforehand.

DPABISurf Installation on Windows

Chao-Gan Yan

1.     Update to latest Win 10 or Upgrade to Win 11.

2.     Enable Virtual Technology in BIOS

2.1.  Restart -> Enter BIOS (during rebooting, hit enter and then F1 or FN+F2)

2.2.  Enable “Intel Virtual Technology”

3.     Install WSL

严老师好，各位老师好，

        我在用DPARSFA对rest-fMRI数据进行预处理后，用DPABI-QC-Generate Group Masks生成mask用于统计，但生成的mask与常见的mask不同，看起来像是经过了旋转之后纳入了部分脑外信息（请参见附上的GroupMask90percent.nii），我检查了每个被试的wAutoMask，仅发现部分被试mask有脑内信息缺失，但都没包含脑外部分（如附图wAutoMask1&2.png），当时的预处理过程见附图Preprocess.png。想请教各位老师为什么生成的GroupMask会出现这种情况？这样的mask应该会影响统计了，请问该如何处理呢？

         多谢各位老师解惑，盼回复！

Hi,

Thanks for leting me join the foroum. I am using DPARSFA on Matlab R2019b. I was practicing using online sample data for DPARSFA and it run up to some point (Bet) but at the end I got the below error:

Hi,

Using dpabi, I have successfully pre-processed all subjects in ADNI that include both "resting_state_fMRI" and "MPRAGE SENSE 2" files.

It seems to me that only 770 subjects in ADNI have resting_state_fMRI data.

My question is: are fMRI data always needed to run the pre-processing with dpabi (as I have already done) or is there also a different way that does not require fMRI data?

Thanks,

Dimitris
