ROI Regressor calculation using Taylor series

dear rest-team,

I am interested into the adaptation of the time course calculation of different ROI regressors in REST in the following way:
For the reason of small correction of time-shifts the idea is to differentiate the time courses, similar to the idea of taylor series:
               f(t)=f(t=0)+ df/dt I(t=0) + d^2f/d^2t I(t=0)+...

Any feedback towards this idea and its potential implementation possibilities in REST would be highly appreciated,

method about REST

i am just reading a review :Default-mode brain dysfunction in mental disorders: A systematic review.  in this article the REST software is mentioned as a methods and measurement models to investigate the DMN.it is said:
  "The assessment of resting brain networks using the BOLD
response may be achieved through a number of methods. Two of
which, region-of-interest (ROI) seed-based correlation approaches
and ICA, are most commonly employed in the literature."

Fix the error of reading and writing NIfTI images in REST on multiple OS (especially 64 bit linux)

Since the module of reading and writing NIfTI images in REST is based on some spm compiled files, you may encounter the problem of “Error using ==> rest_WriteNiftiImage at 92” if you use the most recent OS.

Please do the following steps to fix this problem:
1. Please install SPM5 (or above release) and compile the mex files correctly according to http://en.wikibooks.org/wiki/SPM/Installation_on_64bit_Linux.
2. Please install the latest release of REST.
3. Run the function: REST_Fix_Read_Write_Error. Please click here to download it!

配准

我想把一个非MRI图像配准到标准脑上进行统计分析,就比如是reho图像,因为在标准脑上做了感兴趣区的模板,所以想配准。我先用3D像配准到标准脑上得到配准参数,利用这个参数将reho图像配准到标准脑上,最后在MATLAB中读取数据时出现了很多的NaN,不知道怎么处理。希望得到各位老师和师兄们的帮助。

the problem when i use the Functional connectivity

when i use the Functional connectivity to analysis a patient's data,i meet a problem ,I think i  finish the programme as suggested in the video,but after i typing the DONE ALL,there is an error jumping out:

Expection occured:
Error using==>rest_Writeniftilmage at 92 Meet error while writing the data,

i do not know what that mean,hope can be told as soon as possible.thanks.

Problem reading images

 Hi,
REST seems to have trouble reading in some of my image files, giving me the error below. I'm not sure why this is the case, as it works fine with other data sets. I can view the images and read them into other analysis programs fine. Any help on how I can troubleshoot this problem is much appreciated.
Thanks,
Alex

Seed ROI coordinate

Dear RESTers,
I am using Functional Connectivity of REST 1.3. In the Set ROI-->Voxel wise-->Seed ROI--->Define a seed ROI by setting the center cordinate and the radius, I need to input a set of coordinate. Is that Talairach or MNI?
Thanks

不能做双样本检验

大家好!我又有问题了。按照多媒体教材的步骤,我做到单样本检验,目前都没有问题。现在我把一个病人和一个健康人建好Mask,做双样本检验,在estimate这一步总是显示no sign voxel,result就显示不出结果。还有如果我要比较10个病人和10个健康人群前额叶局部一致性,低频振幅的差别怎么做呢,还是双样本检验吗?好像双样本的Mask只能由一个病人和一个健康对照的做出来。
