Problems with opening well info from .czi-files


#1

Hi,

I have problems with opening .czi multi-position files properly. I take images of multiple positions in each well of 384 plate with 2 or more channels. I’m able to open the files but well numbers cannot be recognized from metadata. Instead, all positions are seen as individual series.

I uploaded examples of my pipeline and TIFF with metadata .xml file. Czi -file is too large to be sent, and therefore I added printscreen how czi-file is detected by CellProfiler. Series 0-1 (or s1 and s2 in TIFFs) are separate positions imaged at well B2 and series 2-3 (or s3 and s4 in TIFFs) are at B3 well. Channels are shown correctly. Any suggestions how wells could be read from metadata?

Thanks,
Nina

Hi Ninar,

(I revisit your issue of “not recognizing well ID”)

It may be better for you to create a .csv file, where you specify the “Well” column (among other crucial columns ImageNumber, Channels etc…) and then use the module LoadData for it.

Hope that helps.

You could also create a CSV just with the ‘Series’ to ‘Well’ mapping (one column with a heading of ‘Series’ that has values of 0,1,2,3,etc, and a column with a heading of ‘Well’ that has values of B02,B02,B03,B03, etc- this should be easy to do with Excel’s fill-in and find-and-replace tools or with a more sophisticated scripting language) and use Metadata’s ‘Import from file’ function to map that information onto the information already existing in the czi header.
