[3dem] Way to read raw pixel size from .eer?

[Takanori Nakane]

Hi,

EER files contain some metadata in TFS-specific
extended TIFF tags (e.g. IFD 65001).
You have to write a script to read it but a dirty way is to just run

strings XXX.eer | less

and go to the bottom.

There is a "sensorPixelSize.height" field.
But I guess this is a physical pixel size of the detector
independent of the magnification.
I don't know if EER contains the pixel size at the sample.

Best regards,

Takanori Nakane
