Read illegal trace lengths?

[GGDRriedel]

I have files that contain traces that are longer than the maximum possible trace length of 2 byte long int that is supposed to be defined in the binary header.

I know the data is there, the files are huge, 12 channels of 5 minutes traces each.

However, I can't seem to find a way to read them "agnostically"

Is there a way? Ignore_geometry=True and strict=False when reading don't seem to do anything.

My only last option is probably to write some own reading routines converting directly from the binary data, however, i would like to not do that.

Any tip would be appreciated

Where did you find reference to the ignore_geometry or strict flags?

[GGDRriedel]

Ah dang, sorry, wrong library.
trying segyio at the same time.

Anyway, the question still persists :p

[rob-smallshire]

Do you have trace length data in a header, say in a four-byte int or something, or do you just know know the trace length some other way?

[GGDRriedel]

The data is from a ground motion sensor that unfortunately records into SEGY for some reason.

I know that the traces are 5 minutes long with 1 ms sampling interval, the SEGY shows 12 channels(like it's supposed to) as 12 traces.

So exactly 5 * 60 * 1000 = 300000 samples per trace every time?
