dials.find_spots_server/client

Introduction

A client/server version of dials.find_spots with additional analysis including estimation of resolution limits. Intended for quick feedback of image quality during grid scans and data collections.

On the server machine:

dials.find_spots_server [nproc=8] [port=1234]

On the client machine:

dials.find_spots_client [host=hostname] [port=1234] [nproc=8] /path/to/image.cbf

The client will return a short xml string indicating the number of spots found and several estimates of the resolution limit.

e.g.:

<response>
<image>/path/to/image_0001.cbf</image>
<spot_count>352</spot_count>
<spot_count_no_ice>263</spot_count_no_ice>
<d_min>1.46</d_min>
<d_min_method_1>1.92</d_min_method_1>
<d_min_method_2>1.68</d_min_method_2>
<total_intensity>56215</total_intensity>
</response>

  • spot_count is the total number of spots found in given image

  • spot_count_no_ice is the number of spots found excluding those at resolutions where ice rings may be found

  • d_min_method_1 is equivalent to distl’s resolution estimate method 1

  • d_min_method_2 is equivalent to distl’s resolution estimate method 2

  • total_intensity is the total intensity of all strong spots excluding those at resolutions where ice rings may be found

Any valid dials.find_spots parameter may be passed to dials.find_spots_client, e.g.:

dials.find_spots_client /path/to/image.cbf min_spot_size=2 d_min=2

To stop the server:

dials.find_spots_client stop [host=hostname] [port=1234]
