Wed, 11/03/2010 - 23:21sxmu_psychiatry老师您好,我在使用slice viewer时遇到这样的情况: 按照教程的提示,我用slice viewer打开一幅ALFF双样本t检验的图,并进行了多重比较校正的相关设置。但是在看结果报表,也就是点击CL REPORT这个按钮后,不能如教程所述那样显示出相应的结果,在MATLAB中提示: Number of clusters found: 9 ??? Cell contents reference from a non-cell array object. Error in ==>...9522 reads

Wed, 10/27/2010 - 23:38dabaqaz在使用Utilities中REST power spectrum时,顺利得到了某一个被试的频谱图。 但是,我想得到具体的频谱序列的值,不知道该怎么办?我查看了源代码,找到了‘theFreqSeries’这个变量,好像就是我需要的,计划增加几句代码将其输出到一个txt文件中。但感觉有点笨,不知道有没有更好的办法?或者REST软件本来已经有了,只是我没有找到? 另外,好像现在只能一个人一个人地计算频谱,我想给出两组被试各自的平均频谱,是否只能先一个一个地先算好了再计算平均值?...6111 reads

Sat, 10/16/2010 - 12:12lihong敬爱的专家: 你们好,我在做癫痫病人和对照组中分别得到了组内的单样本T检验,现在我想观察组间的T检验情况,但是我想希望单单比较癫痫组和对照组的正性连接,再比较负性连接,因为我在直接将癫痫组和对照组进行双样本T检验,如你们的数据处理视频中所说的做,我发现,有些激活的区域,两个组单样本中其实分别是正负连接,这样可能会导致统计上的放大显著差异,所以我想单单了解正性连接和负性连接的情况。但是我不知道应该怎么样通过rest实现...14941 reads
