All Chorus proteomics datasets have been securely preserved and are now accessible on PROTEOBASE without changes to links, citations, or licenses.
Following the conclusion of NIH funding for Chorus, long-term stewardship of the data was required. EuropaDX partnered with the community to preserve this critical proteomics resource in PROTEOBASE.
For most users, no action is required.
Chorus was created with NIH funding to provide free, cloud-based storage and sharing for mass spectrometry proteomics data.
Chorus grew to serve thousands of researchers worldwide, storing terabytes of valuable proteomics data and enabling scientific collaboration.
NIH grant funding for Chorus concluded, requiring a new home for the data.
EuropaDX pledged to maintain Chorus data as a free community resource within PROTEOBASE, ensuring no data would be lost.
All Chorus datasets are now safely housed in PROTEOBASE with automatic redirects from original Chorus URLs.
PROTEOBASE stands on the shoulders of giants. We are proud to continue the mission that the Chorus team began.
The Chorus Project was a pioneering initiative that transformed how the proteomics community stores, shares, and collaborates on mass spectrometry data. Born from the vision that scientific data should be accessible to all, Chorus provided free, cloud-based infrastructure when most labs were struggling with data silos and incompatible formats.
The team recognized a fundamental problem: while mass spectrometry was becoming indispensable for biomedical research, the community lacked efficient mechanisms for sharing and analyzing data collaboratively. Chorus solved this by creating a platform that made data sharing seamless, regardless of vendor format or institutional boundaries.
For over a decade, Chorus served thousands of researchers worldwide, enabling discoveries that advanced human health. The platform became part of the broader Skyline ecosystem—a suite of freely available, open-source tools that revolutionized targeted proteomics.
At EuropaDX, we are honored to carry this legacy forward. We commit to maintaining the core principles that made Chorus invaluable: free access, open data, and researcher-first design. The proteomics community built something remarkable, and we will ensure it endures.
Yes! All Chorus data has been migrated to PROTEOBASE. You can log in using your existing Chorus email address, and all your projects and datasets are preserved.
Yes. All chorusproject.org URLs automatically redirect to their new locations within PROTEOBASE. Citations and bookmarks will continue to work.
Absolutely. PROTEOBASE maintains the same commitment to free, open access that Chorus established. There are no fees for data storage, sharing, or access.
All licensing terms are preserved. Data that was public under CC0 or CC BY remains under the same license. Private data remains private until you choose to release it.
EuropaDX is a life sciences software company that builds the EuropaXp platform for multi-omics data analysis. We committed to preserving Chorus data as a service to the proteomics community.
