XDS should never crash (if it terminates with an error message, this does not count as crash). If it does, it is either a bug in the program which should be brought to the attention of Wolfgang Kabsch or Kay Diederichs, and will be fixed, or it is a problem with your computer. | XDS should never crash (if it terminates with an error message, this does not count as crash).

this means that unfortunately the CPU of your machine is too old to be supported by XDS. This may happen e.g. with old AMD CPUs that don't support SSE2 (on Linux check the ''flags'' field of /proc/cpuinfo for the presence of the sse2 flag). Please find a newer machine - AMD is perfectly fine, but just not the oldest ones. | |||
