It is originally designed for correcting sequencing errors in single-molecule DNA sequencing reads, especially in Continuous Long Reads (CLRs) generated by PacBio RS sequencers. The goal of Sprai is not maximizing the accuracy of error-corrected reads. Instead, Sprai aims at maximizing the continuity (i.e., N50 contig length) of assembled contigs after error correction. .SH OPTIONS .TP .B \-n Show parameters in .I ec.spec and exit. .TP .B \-ec_only Perform error correction only. With this option, .I asm.spec does not need to be passed in, as assembly is not performed. .TP .BI \-now \0yyyymmdd_hhmmss Use an existing .RI result _yyyymmdd_hhmmss directory from a previous run, detect unfinished jobs, and restart at the appropriate stage. .SH SEE ALSO .BR bash5tools (1) .br This program is part of sprai.
