DPARSFA Error Related to Number of Parallel Workers

Submitted by druzgal on Tue, 09/25/2012 - 01:57

Hi,

I have been testing some of the features on DPARSFA V2.2PRE. When running on data from either 1 or 2 subjects using the options from "Calculate in MNI Space: TRADITIONAL Order", everything processes smoothly with parallel workers set at 0. However, when I set the parallel workers to 6 (on an 8 core machine), I get the following error:

Some questions relative to your New edition sofeware

论坛老师好！

有几个问题想看看大家的意见。

1、AlphaSim与Gaussian random-field theory校正那个更严格，分别都更适用于那些情况呢？通常我发现GRF校正voxel P值设为z>2.3，这个值相当于p值多少呢，可否再设的松一点？REST新版加入了GRF校正，可否就该校正的参数设置及意义做一讲解呢？

2、前面严老师说REST中的REST smoothest可以估计校正要求的平滑值，对此有些不解：统计学检验图估计smooth值有什么意义？

3、我发现REST slice viewer与xjview好像有点差异，REST中输入voxel水平的p值0.01，对应T值2.70，而xjview中输入0.01对应T值2.32，不知什么原因？

4、新版DPARSFA中，将协变量剔除提前到filter前有什么意义？

麻烦了！
