Matrix FSL error inv（）：矩阵似乎是奇异的

我正在分析成像数据，使用FSL probtrackx2执行光纤跟踪。但是，我遇到以下错误消息：

错误：inv（）：矩阵似乎是单数

libc++abi.dylib:以std:：runtime\u类型的未捕获异常终止错误：inv（）：矩阵似乎是单数 中止陷阱：6

因为这似乎并不一定与FSL有关，有人能解释这是什么意思吗？ 我不确定我提供的信息是否足够，如有必要，我可以更详细地解释我遇到了同样的问题。 其原因是ROI头部信息和图像头部信息不匹配，尤其是Qform

谢谢你指出错误

可以通过以下脚本修复此问题：

#!/bin/bash
ROI=$1
target=$2 # raw image/ standard image/T1 image, depend on where roi came from.
result_path=$3
# this script is for probtrackx2_gpu, for every roi feed into probtrack2 should have the same qform/sform as raw image or standard image.
mkdir -p $result_path
ROI_name0=`basename $ROI`
ROI_name=${ROI_name0%.nii.gz}
target_name0=`basename $target`
target_name=${target_name0%.nii.gz}
ROI_checked=$result_path/${ROI_name}_hdchecked.nii.gz
cp $ROI $ROI_checked
fslhd_ROI=$result_path/${ROI_name}.fslhd.txt
fslhd_target=$result_path/${target_name}.fslhd.txt
if [ -f $fslhd_target ]; then
        echo $target_name fslhd file exist!
else
        fslhd $target>$fslhd_target
        echo $target_name fslhd file generated.
fi
if [ -f $fslhd_ROI ]; then
        echo $ROI_name fslhd file exist!
else
        fslhd $ROI>$fslhd_ROI
        echo $ROI_name fslhd file generated.
fi
diff $fslhd_target $fslhd_ROI > $result_path/${ROI_name}_${target_name}.diff.txt
ROI_target_diff=`grep -Fxvf $fslhd_target $fslhd_ROI`
if [[ $ROI_target_diff == *"qform"* ]] || [[ $ROI_target_diff == *"sform"* ]] ; then
        echo $ROI and $target are different in qform or sform!
        fslcpgeom $target $ROI_checked -d
        echo copy geom information qform/sform from $target .
fi
echo please use $ROI_checked in probtrackx2.

我也有同样的问题。 其原因是ROI头部信息和图像头部信息不匹配，尤其是Qform
