Again, the most important parameters are [[Obtaining ORGX ORGY|ORGX ORGY]]. Often the software which writes the frames puts these numbers into the headers of the frames. However, these numbers are sometimes wrong, which is why old versions of XDS did not read and interpret headers of frames at all (update: since 2009 XDS tries to extract NX NY QX QY from the header, but nothing else).

:If this line is omitted (''and SECONDS=0''), the whole DATA_RANGE is used. This is usually a good way to proceed. If there is radiation damage, I would advise to use the first half of the DATA_RANGE as SPOT_RANGE. The SPOT_RANGE in principle may comprise a single frame. <br />Attention: if SECONDS= has a parameter >0, a small SPOT_RANGE will be used if SPOT_RANGE is not explicitly provided! | :If this line is omitted (''and SECONDS=0''), the whole DATA_RANGE is used.
