MGnify makes functional results available two separate ways, either per-analysis basis web api, whole study level large files, tab separated (TSV), columns representing results analysis. bulk.dl FALSE, MGnifyR queries web api get results (given functional analyses results may consist thousands entries) may take significant time. Setting bulk.dl TRUE causes MGnifyR determine source study associated particular analysis instead download parse corresponding results file. Since result file contains entries analyses associated study, taking advantage MGnifyR’s local caching single download provides results many future analyses. cases affords several orders magnitude speedup api query case. Unfortunately, column entries per-study results files always directly correspond particular analysis run, causing retrieval fail. principal cause believed running multiple analyses jobs sample. Thus reliability, bulk.dl FALSE default. general recommendation though, try setting TRUE first time getResult() used set accessions. fails, setting bulk.dl FALSE enable robust approach allowing analysis continue. might take though.
