A message like "Note: The following floating-point exceptions are signalling: IEEE_DIVIDE_BY_ZERO IEEE_UNDERFLOW_FLAG" may be printed after running XDS or XSCALE. This is harmless. | |||

Although CCP4 is not required by XDS itself, some of the programs (XDSSTAT, and MTZ file creation in XDSCONV, POINTLESS and COOT) use CCP4 tools or libraries. Therefore, CCP4 should be installed.

Become familiar with the concept and ways to run commands as "root" - google "mac osx become root". All the installation tasks that are run in a Terminal window require root privileges, since some of the programs and their links are written to /usr/local/bin. (As an alternative that does not require root for installation, one may create a directory $HOME/bin and use that for the programs and links. That would also require modification of the $PATH, by a one-time <code>echo 'export PATH=$PATH:$HOME/bin' >> ~/.profile</code>) | Become familiar with the concept and ways to run commands as "root" - google "mac osx become root".
