<div dir="ltr">The one thing to be careful about with a 3D array is that it can get to be too large. I think the Dectris approach of stacking a reasonable number of frames in each of several 3D data arrays is sensible. -- Herbert<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Fri, Jun 24, 2016 at 1:20 PM, Pete R Jemian <span dir="ltr"><<a href="mailto:prjemian@gmail.com" target="_blank">prjemian@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
I want to store a set of images according to the NXsas application definition. In the current case, these images form a time series. NXsas defines /entry/instrument/detector/data as a 2-D image frame.<br>
<br>
What's my storage strategy? Any of these or something different?<br>
<br>
first choice: 3-D frame set<br>
/entry/instrument/detector/data: (frames, rows, columns)<br>
<br>
second choice: single frames in same NXdetector<br>
/entry/instrument/detector/data_frame_1: (rows, columns)<br>
...<br>
/entry/instrument/detector/data_frame_n: (rows, columns)<br>
<br>
third choice: one group for each frame<br>
/entry_frame_1/instrument/detector/data: (rows, columns)<br>
...<br>
/entry_frame_n/instrument/detector/data: (rows, columns)<br>
and link other objects (NXsample, ...) from /entry_frame_1/*<br>
<br>
