StitchIt is a MATLAB package that was originally built for stitching data from the TissueVision 2-photon tomography system. However, StitchIt is sufficiently modular that it can handle other tiled data sets too (e.g. from a slide scanner or tiled images obtained from in vivo experiments using ScanImage). To get started, please read the Wiki. There is a changelog.

With a single command (syncAndCrunch) the user can:

• Pre-process image tiles as they are being acquired.
• Display the last acquired section on the web.
• Automatically stitch data when acquisition completes.
• Send Slack notifications when acquisition completes or pre-processing fails.
• Automatically conduct arbitrary analyses after acquisition completes.

StitchIt has commands for basic tasks such as:

• Stitching subsets of a data set.
• Calculating the average tile for illumination correction.
• Calculating coefficients for correcting for scanning artifacts (experimental).
• Randomly accessing any tile in the dataset.
• Techniques for exploring stitching accuracy.
• Cropping stitched datasets or partition a single stitched dataset into multiple ROIs.

Post-stitching functionality:

• Correction of intensity differences across different optical sections.
• Removal of tile seams in stitched images.
• Down-sampling the dataset to a single multi-page TIFF stack or MHD file.

Clone the repository. Add the code directory and its sub-directories to your MATLAB path. In addition, you will need to acquire the following and add to your MATLAB path:

• Slack MATLAB
• rsync is needed if you want to use the syncAndCrunch tool to process data during acquisition.
• Additionally, you will need the following MATLAB toolboxes: statistics, parallel computing, and image processing.

If you need more information on the installation procedure, please see the Installation page on the Wiki. Stitchit will automatically check if it's up to date whenever the user runs syncAndCrunch.

Please use the project's issue tracker for questions, bug reports, feature requests, etc.
