Convert a bunch of CBF files into EDF format

This simple tutorial explains how to convert a bunch of CBF files to EDF files.

import glob
files = glob.glob("*.cbf")
files.sort()
print("Number of files: %s" % len(files))

Number of files: 200

dest_format = "edf"
dest_dir = "edf_format"

import fabio, os
if not os.path.exists(dest_dir):
    os.makedirs(dest_dir)

%%time
for onefile in files:
    dst_name = os.path.join(dest_dir, os.path.splitext(onefile)[0] + "." + dest_format)
    fabio.open(onefile).convert(dest_format).save(dst_name)

CPU times: user 2.36 s, sys: 2.84 s, total: 5.21 s
Wall time: 5.64 s

print("The overall speed is %.1f frame/second"%(len(files)/5.64))

The overall speed is 35.5 frame/second

Conclusion

This simple tutorial explains how to perform simple file conversion. It is likely to be limited by the bandwidth available for the hard-drive of your computer or by the compression/decompression algorithm as it the case here for CBF decompression.
