needs to be mined from various publications and multiple repositories like SCP, HCA, GEO, etc. And this is just the beginning. The researcher then has to spend a huge chunk of time extracting and preprocessing this data because it will be present in different file formats, which may not be easily accessible or compatible with all data analysis tools. Here’s a glimpse of the single-cell datasets on Elucidata’s data harmonization platform- Polly. Polly harmonizes unstructured single-cell data with a configurable, transparent, and granular curation process as per your inclusion/ exclusion criteria to accelerate downstream analysis. Another challenge is incomplete or poorly described metadata (cell types, experimental conditions, sample information, etc.), making it challenging to interpret the results.
