Top 10 Tips for Faster MRIcron Workflows

MRIcron vs. MRIcroGL — which to use

Quick summary

• MRIcron: lightweight, stable 2D/3D image viewer focused on simplicity, lesion drawing, ROI creation, and broad compatibility with older systems. Good for quick inspections, manual ROI work, DICOM→NIfTI conversion (via bundled tools), and scripting simple workflows.
• MRIcroGL: modern successor with GPU-accelerated 3D rendering, high-quality surface/volume renders, scripting for publication‑quality figures, and active feature development (MOS AIC, export options, dcm2niix integration). Better for polished visualizations, large overlays, and interactive 3D work.

Choose MRIcron if

• You need a minimal, stable viewer with simple ROI/lesion tools.
• You work on older or low‑resource machines.
• You prefer a straightforward interface for quick checks and manual edits.

Choose MRIcroGL if

• You want high‑quality 3D surface/volume renders and mosaic exports.
• You need GPU-accelerated performance for large datasets or complex overlays.
• You want advanced scripting, export options, and features for publication figures.

Practical guidance

• Use MRIcron for day‑to‑day manual ROI work and quick checks.
• Use MRIcroGL when creating publication images, complex 3D visualizations, or converting/organizing DICOM with dcm2niix.
• Both tools interoperate: convert/prepare in one and render/export in the other as needed.

Compatibility & support

• Both read common neuroimaging formats (NIfTI, some DICOM workflows).
• MRIcroGL receives more active UI/feature updates; check NITRC or the developer’s site for the latest builds and release notes.

If you want, I can recommend which to install for your OS and GPU, or give a short how‑to for a common task (e.g., overlay thresholding or exporting publication PNGs).
