Dear cryoSPARC community.
I am trying to run an 2D classification of externally extracted particles. The stack contains almost 900.000 particles of 300*300 dimension. When I try a classification of the imported particle stack, I receive the following error:
[CPU: 5.01 GB] Traceback (most recent call last):

data = n.fromfile(file_obj, dtype=self.dtype, count= n.prod(self.shape)).reshape(self.shape)
ValueError: cannot reshape array of size 0 into shape (300,300)
I splitted the dataset in 3 fraction of 300000 particles within cryoSPARC and for the first two fractions the classifications runs, for the last it still fails with the same error. Also I tried downsampling but this process fails with the same problem.
Can someone explain what might be wrong? Is there a problem with the imported file, maybe a specific image within the stack.
Thanks for you help and kind greetings.
