您好，想问一下读取nii数据和.mat数据 在结果上有什么影响么？ mat 能转换为.nii么

发生异常: IndexError
index 1 is out of bounds for dimension 2 with size 1
File "/root/autodl-fs/PET-Reconstruction/model/sr3_modules/diffusion.py", line 280, in p_losses
x_extra = x_in['HR'][:, np.newaxis, k, :, :]
File "/root/autodl-fs/PET-Reconstruction/model/sr3_modules/diffusion.py", line 293, in forward
return self.p_losses(x,ax_feature, fr_feature, *args, **kwargs)
File "/root/autodl-fs/PET-Reconstruction/model/model.py", line 178, in optimize_parameters
l_pix = self.netG(self.data,ax_feature, fr_feature)
File "/root/autodl-fs/PET-Reconstruction/train.py", line 90, in
diffusion.optimize_parameters()
IndexError: index 1 is out of bounds for dimension 2 with size 1

想问一下这是咋回事？

还有一个问题就是 您提供的dataset 怎么处理呢？应该使用您提供的哪个代码进行预处理。mat文件是可以转换成对应的nii格式的把？
