    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.

    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:

    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 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?
