Clustering generates varying results every trials.

Is there anyone here who performed k-means clustering using DynamicBC? I would like to ask if you get varying results if you perform multiple trials in k-means clustering with matrix correlation as the metric. Is this really normal for k-means clustering even for other programs? How should I be able to normalize this because the results vary a lot per trial? Any reply is greatly appreciated. Thank you!

关于内侧颞叶脑区进一步细分的问题

各位老师、同学,大家好!
我在分析数据的时候遇到一个问题,一直没有解决。就是关于内侧颞叶中进一步的分区问题。我想要区分出海马、海马旁回,嗅周皮层来,但是这个嗅周皮层在AAL模板中并没有。查文献得知这个区域需要手动在结构像上描绘出来,再标准化。但是我现在不知道要在什么软件上进行描绘,文献中也没有说,然后又要怎么进行标准化。
不知道有没有做过这方面研究的同学,或者老师能解答我的问题,万分感谢!

平均灰质模板的构建问题

各位老师,我按照VBM说明书用dartel tool(creat template)生成了平均灰质模板,Template_0到Template_16 这17个文件,请问哪一个是可用的模板文件?是最后一个?还是根据肉眼精度来判断?肉眼看template_6和template_13比较清晰,最后生成的template_16并不清晰。
