Hi, SU internal data format is derived from SEG-Y rev0. So, the number of samples per trace is coded as a positive 2 bytes integer. Consequently the number of samples per trace is limited to 2**16=65536 samples.

This is enough for most of "classical" seismic data but can be a limitation for some uncorrelated data or continuous node recording.

Enjoy SU (anyway !)

Hi all,

I am facing an issue with a large file. Seismic Unix has limitations when processing, reading, or writing a number of samples beyond approximately 61,500. Could you please suggest how to increase this limit for handling larger datasets?
