Plugin to perform IMS to microscopy registration using laser ablation marks.
napari plugin to perform MALDI IMS - microscopy registration using laser ablation marks as described in Anal. Chem. 2018, 90, 21, 12395–12403. This plugin is a work-in-progress but is mostly functional.
N.B. This tool is NOT a general purpose registration framework to find transforms between IMS (MALDI or otherwise) and microscopy. It is built to align MALDI IMS pixels to their corresponding laser ablation marks as captured by microscopy AFTER the IMS experiment. This approach has the advantage of providing direct evidence of registration performance as IMS pixels are aligned to their explicit spatial origin in microscopy space, improving overall accuracy and confidence of microscopy-driven IMS data analysis.
You can install
napari-imsmicrolink via pip:
pip install napari-imsmicrolink
Typical experiment workflow¶
Acquire pre-IMS microscopy (autofluorescence, brightfield) - optional
Perform normal IMS sample preparation.
Acquire post-IMS microscopy (autofluorescence, brightfield) with matrix still on sample that reveals laser ablation marks.
Gather IMS data that contains XY integer coordinates for the IMS experiment (.imzML, Bruker spotlist (.txt, .csv), Bruker peaks.sqlite (FTICR), Bruker .tsf (TIMS qTOF only))

Once registered, use
wsiregto align other microscopy modalities to IMS-registered post-IMS microscopy
