Please simply click "Schedule Job" when you filled all input fields.

Please make sure your contour level is lower than your focused region. This is absolute density threshold, not standard deviation.

If you are not sure, just use threshold 0, our model can automatically detect the structure regions.

CryoREAD is designed for map at better than 5A resolution.

Resolution information is needed for refinement by phenix.real_space_refine.

If you do not know sequence information, you can skip to upload the fasta file.

We accept fasta files that includes proteins, where protein sequence will be automatically ignored.
