Bonjour Marc,
I read the same file with 2 versions of geopsy (2.6.3 and 2.7) (using window 7). This file comes from a classical GEODE acquisition system. I have checked the parameters they are all the same (frequency sampling, dt , number of samples).
The view is drastically different (see attached files).
Any idea of the problem?
Have a nice day

This is now fixed for the next minor release (geopsy pack 2.3.1).
Effectively, for geopsy version 2.6.3, corresponding to GeopsyCore library version 3.2.3, loading of SEG-2 with 20 bit floating-point format (based on Digital field tape format standards -SEG-D (2.5-byte binary exponent data recording method, demultiplexed) was working with a rather ugly code. Since then this code was cleaned up but probably not tested because this option for SEG-2 format is not so common. Now the code is clear and correct.
Thanks for your report.
