Description

Current showinf (at ad334917) shows various odd metadata for https://www.openmicroscopy.org/qa2/qa/feedback/17260/ including,

Component Count #1: 1
Component Count #2: 1
Component Count #3: 1
Data: i�%���¬����c?�����c�i�%��
Desc: Ti ZDrive
Detector: 0

and

bZInverted: false
bZPosAbsolute: true

That dCropZoom bit certainly seems to confuse Insight, as shown in the attached screenshot. (On my desktop I'm using a UTF-8 locale.) It might be nice to better handle this non-ASCII character data.

Screenshots of QA 17260 opened in NIS Elements have been uploaded to data_repo/inbox/qa-17260-investigation/. The excitation wavelengths in particular are missing, when Elements shows that they should be 405.0, 488.0, and 561.0 for each of the 3 channels. I'd assume it's related to what's going on here, as both are indicative of one or more metadata blocks being incorrectly parsed (possibly an incorrect starting offset?).
