Cloud Storage Input/Output

cloudreg.scripts.download_data.download_data(s3_path, outfile, desired_resolution, resample_isotropic=False, return_size=False)

Download whole precomputed volume from S3 at desired resolution and optionally resample data to be isotropic

Parameters:

• s3_path (str) – S3 path to precomputed volume

• outfile (str) – Path to output file

• desired_resolution (int) – Lowest resolution (in nanometers) at which to download data if desired_resolution isnt available.

• resample_isotropic (bool, optional) – If true, resample data to be isotropic at desired_resolution.

Returns:

Resoluton of downloaded data in microns

Return type:

resolution

cloudreg.scripts.download_data.get_mip_at_res(vol, resolution)

Find the mip that is at least a given resolution

Parameters:

• vol (cloudvolume.CloudVoluem) – CloudVolume object for desired precomputed volume

• resolution (int) – Desired resolution in nanometers

Returns:

mip and resolution at that mip

Return type:

tuple
