运行新版DPARSF遇到问题

Submitted by lynnrain on Fri, 12/04/2009 - 19:52

各位RESTers，我在运行DPARSF的时候遇到问题。
序列情况，SIEMENS TRIO TIM 3T，梯度回波EPI序列，TR/TE 2000/30, FOV 256*256, Resolution 64*64, 每卷共36层，层厚 4 mm, 层间隔0mm, 翻转角 90度。共210个时间点。
运行环境为VISTA下的matlab 2009b，SPM8b（更新至9月的版本），DPARSF_V1.0_091201.和 REST2007V1.3_091201.
我尝试运行采集的一个受试者图像，功能DICOM图像建立于matlab工作目录下的FunRAW/Subject001目录下。
采用DPARSF处理数据的时候，当运行到显示如下窗口时停滞

同时matlab的命令窗口提示错误如下：

detrend: out of memory

Submitted by frog on Thu, 12/03/2009 - 08:37

 Dear Yan,

Recently I have used Rest and also DPARSF to do the detrend analysis. I have 940 volumes per subject. But when I run only one subject's smoothed 940 data to do the detrend analysis both Rest and DPARSF reporting out memory error. If I merely cut the data to 100 volumes then to do detrend analysis, everything goes well. So, here I wonder whether there is solution to deal with the situation? Thanks a million!

best,

frog

New releases of REST and DPARSF

Submitted by YAN Chao-Gan on Wed, 12/02/2009 - 00:54

Dear All!
        New releases of REST and DPARSF are coming now.
        I am SOOOO sorry for the delay of this release.
        I have said we may release it in this September, but it delayed again and again. Please forgive me since I was involved in revising a paper and rebuilding my house which was ruined by a flood this summer.
        Thanks for Mr. DONG Zhang-Ye and Mr. ZHU Wei-Xuan's work, we published this release eventually. Some users are using the close test version of this release, especially for REST AlphaSim, now can turn to this public release. Thanks for your patience.
        Since lots of functions are added or revised, there may be some bugs. Please report to us if you find any.
        Best wishes!

individual functional connectivity maps in SPM

Submitted by Duke_Han on Tue, 12/01/2009 - 04:32

Hi,

Is there a way to visualize the functional connectivity maps on a individual basis in SPM?  I know I can do second-level group analyses, but I am interested in looking at functional connectivity on an individual basis.  Any advice would be helpful.  Thanks.

Duke
