Data Reduction Frequently Asked Questions

What do I do if I get the messaged "CPL initialisation failed" in gasgano?

If you get an error message like:

    Lost output message: 10:52:04 [WARNING] CPL-messaging
    initialization failed:
    Lost error message: 10:52:04 [ ERROR ] Dumping all 1 error(s):
    Lost error message: 10:52:04 [ ERROR ] [1/1] 'File cannot be created'
    (8) at cpl_msg_set_log_level:cpl_msg.c:874

Likely you do not have write access for the current directory. Change directory permissions or change the directory itself to somewhere where you can create files.
