efetch, esummary - retrieve results from an NCBI Entrez search

efetch and esummary retrieve results from either an Entrez Direct pipeline or an  immediate  lookup  (via
       -db and -id or -input).  esummary is equivalent to efetch-formatdocsum.

       efetch  is  also  the  name  of  an  AceDB tool for consulting local sequence databases.  To resolve this
       ambiguity, Debian systems with  both  AceDB  tools  and  Entrez  Direct  installed  arrange  for  AceDB's
       executable to have the name efetch.acedb(1) and for efetch to be a wrapper script that examines its usage
       and proceeds to run whichever of efetch.acedb(1) or efetch.ncbi looks like a better fit.

              Bit flag specifying extra features.

       -showgaps
              Propagate component gaps.

   SubsetRetrieval-startN
              First record to fetch.

       -stopN
              Last record to fetch.

              Direct sequence retrieval in groups of five.

       -immediate
              Express mode on a single record at a time.

       -json  Convert adjusted XML output to JSON.

       -help  Print  usage information, complete with examples of notable -db/-format/-mode combinations (in the
              case of efetch) and of supplying accessions in the -id field (in the case of esummary).
