大家好,请帮忙分析这篇文章的数据是怎么处理的

最近在看一篇文章,有些数据分析方面的问题搞不清楚,如果有人处理过类似的数据,请不吝赐教。谢谢!
MR Image Acquisition
Images were acquired with a multislice, singleshot EPI sequence to achieve whole brain coverage: 40 axial slices, TR=5 seconds, TE =35 illiseconds,
3.5-mm slice thickness, in-plane resolution 1.8 mm by 1.8 mm at the Magnetic Resonance Imaging Facility, Salford Royal NHS Foundation Trust, Salford. A SENSE 8-channel head coil was used for radio frequency transmission and reception.

normal ditribution before RFX ananlysis

Hi all,
In the article "Detection of functional networks in the resting brain" there was a step before group analysis involving transforming the individual Reho data to normal distribution. Has this function been implemented in REST ? If yes, what specific method is being used?

Thanks,

今天碰到的几个问题

近期碰到几个问题
拿出来大家看看:

做统计分析结果呈现的时候,因为是手动配准,用的AFNI tlrc坐标,最终结果在各种工具中呈现结果不同:
rest slice viewer效果最好,与模板匹配


同样的结果放到MRIcroN就不匹配(我用的模板和mask是同源的)
可能是MNI坐标与tlrc坐标不同的关系

在spm里面也一样 不匹配:

dparsf潜在的bug?

亲爱滴们:

今天碰到这样一个问题,焦头烂额:
由于这批数据需要手动配准,所以我的处理流程如下:
1. 用dparsf批处理至realign。
2.用spm做coregister.
3.用AFNI转换格式后做Normalize
4.转换个格式后,将得到的EPI相文件放入FunImgNormalized文件夹。
然后启动dparsf,
先跳过Smooth做的ReHo,很顺利,detrend, filter, reho...没有任何问题。
然后继续用dparsf做alff以及falff,操作过程如下:
    -matlab下输入dparsf
    -依次去掉smooth前所有的勾
    -选择工作目录
   - 输入时间点190
   - 选择自定义模板

help 3: Rest Dicom Sorter

坛主,
这批数据比较早,2005年GE机器,TR 1s, 16sl, 200TR.
使用Sorter时候报错:

??? Error using ==> mkdir
系统找不到指定的文件。

 

Error in ==> rest_DicomSorter at 38
        mkdir(dirname);

help 2: dparsf

hi,

the previous error i brought up was fixed by adding the line
    "rest_Fix_Read_Write_Error"
before initializing dparsf.

however, the time between pressing the bottom "run" and actual data precessing is much longer  in the linux environment than windows (just now i experienced a 15 min lag).
so is the time for data precessing.
what might the problem be? how can i fix it?
i'm currently using double systems on my laptop, which are windows XP and linux fedora ver 12.

左右脑位置

各位老师:
      现在我有一个关于左右脑的问题想向各位老师请教一下。附件中是一个mask,我把它命名为cacudate(L),因为用mricro打开叠加在CH2模板上显示的是左侧。想请问老师这个mask是不是就是对应在核磁机上打开看到的左侧,是真实人脑的右侧呢?
      非常感谢!

请教:REST DICOM sorter报错

dicom文件穿不上来,提示
 Only files with the following extensions are allowed: jpg jpeg gif png txt doc xls pdf ppt pps odt ods odp img hdr nifti nii.
我把dicom的文件重命名,后面加了后缀.jpg传上来,能帮我看看吗?
还有一个问题请教,关于slice view能不能也像xjview的volume一样,出一个表格,然后点表格内的坐标,图像的十字架就可以自动定位到坐标所在的位置?
