Export image metadata

[Orotomah Ameh Great]

Hi All, 

Thank you for your help the other time to myself and numerous students worldwide.

I hit a bit of road block trying to extract the Metadata of a particular "mz" value so I can visualize the image in MATLAB.

I extracted the "tic" Metadata using "Mice_Brain@Metadata" and passed this into a dataframe, reconstructing and plotting the image in MATLAB. However I am interested in the ion density image of a particular "mz"  number. 

I passed the image plot into a variable X and tried to convert this variable into a data frame so I could write it into a CSV file and reconstruct it for MATLAB, but this didn't work. I keep getting the response "cannot coerce class vizi_plot" to a data frame.

Could you please advise on how to go about this if it is possible ?

Kind regards,

Great.

It sounds like you are trying to export the image data itself, not metadata.

Slicing an image as an array is documented here: https://bioconductor.org/packages/release/bioc/vignettes/Cardinal/inst/doc/Cardinal3-guide.html#slicing
