Eighth Coding Week: The Final Coding Week!#
Hello everyone, one last time!
This was the eighth and final coding week of my GSoC project with DIPY.
Most of the main implementations had already been completed, so, as in the previous week, my work focused on polishing the remaining contributions, addressing review comments, improving tests and documentation, and discussing some final design decisions with my mentors.
Alongside the coding work, I started preparing the final report for my project. It brings together the main implementations, experiments, results, and lessons from the summer. The report is already publicly available here:
It will also be published through the DIPY website once it is complete.
Contributions Summary#
During my GSoC project, I opened ten pull requests covering registration metrics, performance improvements, bug fixes, documentation, and SynthSeg utilities. The following table summarizes these contributions:

Final Thoughts#
With the coding period coming to an end, it feels like the right moment to look back at everything these last months have taught me.
This project showed me that implementing an idea is only one part of contributing to scientific software. In many cases, the most difficult and valuable work comes afterwards: simplifying the implementation, testing unusual cases, documenting decisions, discussing APIs, responding to reviews, and making sure that every change fits naturally into a large and established codebase.
GSoC has been my first real experience contributing to open-source software, and it has completely changed how I see this kind of work. I came into the program hoping to implement a project and learn from the process, but I leave it wanting to keep contributing, collaborating, and improving software that can be useful to others.
Although the official coding period is coming to an end, this does not really feel like an ending. I still plan to support the pull requests that remain under review, stay involved with DIPY, and continue participating in the wider open-source community.
In that sense, the end of GSoC feels much more like the beginning of a longer journey—one that I am very excited to continue.
I am very grateful to my mentors, Serge Koudoro, Atharva Shah, and Jong Sung Park, for their guidance, patience, thoughtful reviews, and trust throughout the project, and for making me feel welcome from the very beginning.
