Work History

May 2026

4 Commits • 2 Features

May 1, 2026

Monthly summary for 2026-05: Delivered robustness and usability enhancements across spm/spm and spm/spm-docs. Key features include flexible input handling for Spm_BIDS_file with array entries for all fields and optional session, plus improved file path construction, increasing input versatility and preventing errors when session is omitted. Time window alignment now auto-adjusts mismatched windows with a warning, ensuring consistent processing even with imperfect input. In docs, Neuro-1 Tutorial for the development version was updated to reflect latest changes (download links and channel specifications), aiding developer onboarding and testing. These changes reduce runtime errors, promote smoother user experiences, and accelerate development cycles. Technologies demonstrated include MATLAB/SPM-like scripting, input validation, automatic data alignment logic, and documentation maintenance.

April 2026

June 2025 monthly summary for spm/spm focusing on data integrity and bug resolution. No new features were released this month; the team prioritized stabilizing data pipelines and metadata handling through targeted bug fixes and code quality improvements.

May 2025

6 Commits • 2 Features

May 1, 2025

May 2025 summary: Delivered targeted improvements to data quality control, data standardization, and Neuro1 OPM-MEG workflows. Implemented UI enhancements, robust data handling, and expanded documentation to accelerate reliable analyses and user onboarding across spm/spm and spm/spm-docs.

January 2025

1 Commits • 1 Features

Jan 1, 2025

January 2025: Delivered a BIDS-compliant Filename and Path Generator for spm/spm. Implemented MATLAB function spm_BIDS_file.m to generate BIDS-ready filenames and folder paths with flexible parameters (subject, session, task, run) and optional descriptors. The function constructs full paths, extracts directory and filename components, and reports whether the target file already exists to prevent duplicates. This feature enhances data organization, reproducibility, and downstream data-processing workflows, reducing manual effort and errors in data curation.

November 2024

1 Commits

Nov 1, 2024

Month: 2024-11. Focused on stabilizing the Glass BF workflow in the spm/spm repository. Delivered a targeted bug fix and reinforced default behavior to prevent misconfigurations. The work emphasizes reliability, correctness, and maintainability with clear commit traceability.
