Hi Dan, I have several versions of LAS data (1.2,1.3 and 1.4) and would like to process them.
I’m using a virtual desktop with Gnome terminal and I think it’s a Centos OS. Below is the conda list from my new installations. Another colleague from Adam’s team is also experiencing the similar “seg errors”. So far we are unable to troubleshoot this problem, when you get a chance can you please provide us some suggestions so that we can create a stable version.

You have ‘-i’ followed by ‘--input_proj’, rather than the input. This is interpreted as having the input as ‘--input_proj’, then you are using ‘GDA94MGAZn55.wkt’ as an argument without a flag. Also it needs to be a file not a web address. As for reverting to a previous version from an earlier email I was under the impression you needed LAS 1.3 support which is only available in the latest version (hence why you needed the Linux version not the old Windows version). For the seg fault, I’m not sure why this is happening. Are you sure there isn’t a problem with the input file? Do you have read access to the input file and write access to where you are trying to write to? If it was working before on the same file in the same location can you provide me details of your system (OS etc.,) also the outputs of: conda list At the moment you haven’t provided much information to go on.

Hi Narsimha, From my earlier email: You will also need to pass in the projection as a WKT file using --input_proj as it is currently segfaulting when trying to read the projection from a LAS 1.4 file. Is this a LAS 1.4 file? If so you need to pass in a text file containing the projection in WKT format using the --input_proj flag. If you don’t already have a WKT file you can download one from http://spatialreference.org/ Thanks, Dan On 17 Aug 2016, at 05:26, Narsimha Garlapati <narsimha.garlap...@anu.edu.au<mailto:narsimha.garlap...@anu.edu.au>> wrote: Hi Dan, Finally with the kind support from NCI, I have managed to install the latest spdlib.
