Extracting metadata on lif files

[phm]

Hi,
I'm trying to extract metadata from lif files with Bioformat macro extensions. I would to read the metadata :
"TileScan_001 Tile|FieldX 5" in the metadata file :

Code: Select all

TileScan_001 HardwareSetting|ScannerSettingRecord|nFormatInDimension #1   1024
TileScan_001 HardwareSetting|ScannerSettingRecord|nFormatOutDimension #1   1024
TileScan_001 HardwareSetting|ScannerSettingRecord|nLineAccumulation #1   1
TileScan_001 HardwareSetting|ScannerSettingRecord|nLines #1   1.00000000000011
TileScan_001 HardwareSetting|ScannerSettingRecord|nPages #1   1
TileScan_001 HardwareSetting|ScannerSettingRecord|nSections #1   4
TileScan_001 Image name   TileScan_001_Merging001
TileScan_001 Reverse X orientation   false
TileScan_001 Reverse Y orientation   true
TileScan_001 Tile|FieldX   5
TileScan_001 Tile|FieldY   6
TileScan_001 Tile|PosX   0.04367906455037
TileScan_001 Tile|PosY   0.00536585662768


with the function

Code: Select all

Ext.getMetadataValue("TileScan_001 Tile|FieldX", Col);


However it return always 0
By the way from czi file I have no problem to read metadata (others) with the same function ???

Hi Philippe,

It depends on the type of metadata being read, the function you have attempted is used to retrieve global metadata for the entire file.

For series specific metadata you should be able to retrieve it using the function

Code: Select all

Ext.getSeriesMetadataValue(field, value)

Looking at the documentation and it appears that this series metadata function was missing so it would certainly have been very confusing. Our apologies for this oversight, I have opened a PR to correct the documentation for the future: https://github.com/openmicroscopy/bioformats/pull/2943
