I'm testing Jalview starting Chimera (1.10.1) with RESTServer on a Windows 7 machine without gzip installed.

On starting the Chimera process:

new ProcessBuilder().start("chimera.exe", "--start", "RESTServer")

I get two lines of response:

Cannot execute 'gzip': no automatic decompression of .Z files

REST server on host 127.0.0.1 port nnnnn

which is ok - I can get the REST port number I need and carry on.

Am I safe to ignore the other message? I can't see what file (I assume part of the Chimera installation) it is arising from.

Thanks,

Mungo
