Worked on the ayalab1/neurocode repository, focusing on improving data preprocessing reliability in MATLAB. Addressed a critical bug in the concatenateDats.m script by replacing a fixed-length substring extraction with a regular expression-based approach for parsing recording times from filenames. This update enabled robust extraction of the last six digits, accommodating milliseconds and supporting diverse filesystem formats. The change enhanced the stability and integrity of data ingestion workflows, reducing data drift and improving the accuracy of downstream timing analyses. Demonstrated proficiency in scripting and regular expressions, delivering a targeted solution that strengthened the overall preprocessing pipeline without introducing new features.
