after -O you should use "-GLOBAL_SHIFT AUTO"

And which version are you using by the way?

Hi

With global shift auto it give the same error. I have tried both latest stable and alpha releases.
I found a workaround using lastools. It was able to convert the ASC to LAS, but it adds a step to the procedure.

Hum, then it must be an issue with the 'LAS_SHIFT' value. Can you maybe share the file with me so that I can test that on my side? (admin [at] cloudcompare.org)
