reconstruction of image maldi

[BENDOU]

Hi,

Hello,

I’m working on MALDI images. At first I have a sample of a region of tissue (25x 20 pixels) obtened using BRUKER instrument, then I converted these pixels files (. Baf) to (. csv) files using the software CompassXport. Each file .csv(i.e; pixel) contains two columns, the first one is for m/z and the second for the corresponding intensities. My problem now is how to reconstruct my image from these files .csv? how to convert my intensities in value between 0 and 255? I supply you if you can guide me or provide me the documentation for this kind of transformation.

thank you

The data can be imported in Excel and displayed as heatmap. Or modify the code described in this forum (Excel to Analyze Conversion) to export the data for BioMap.
