Dear Fulvio,

Mosflm attempts to read the phi start and end angles from the image header, but on some synchrotron beamlines this information is not written correctly to the header, which would explain the error message. Alternatively, if you have really collected a "still" image (oscillation angle of zero) you will also get this message.

You there need to set the oscillation angles with the AUTOINDEX keyword, eg

AUTOINDEX IMAGE 1 PHI 0 1

for a one degree oscillation image starting at phi=0. If you really have collected a still image, set the end phi value to be 0.001 greater than the start phi value as a workaround.

This is explained in the online help for ipmosflm (just start the program and type "help" at the prompt) as part of the description of the AUTOINDEX keyword.

Best wishes,

Andrew Leslie

Dear all,
I received this error message from ipmosflm. I started ipmosflm from
terminal, entered the detector (detector marccd) loaded the image and
then press go. Can anyone help me?

"Phi values have not been specified on AUTOINDEX keyword, and
oscillation range from image header is zero. Supply phi values on
AUTOINDEX keyword"

Thanks to all in advance
