take a look into config.log to read the error message why your gcc-compiler does not work? You should start at the end of the log file and scroll backwards until you find the error message. Best, Tim On 03/03/2014 03:51 PM, wu donghui wrote: -- Forwarded message -- From

You might have to test if it is salt/detergent or protein crystal first. If it is really protein crystal, never give up and for needle crystal, generally it is difficult to optimze, however in most cases, the diffraction is well enough. If it is protein crystal, as some researcher has mentioned,
