This function checks the position of the SNP within the trimmed sequence tag and identifies those for which the SNP position is outside the trimmed sequence tag. This can happen, rarely, when the sequence containing the SNP resembles the adaptor.
The SNP genotype can still be used in most analyses, but functions like gl2fasta() will present challenges if the SNP has been trimmed from the sequence tag.
Not fatal, but should apply this filter before gl.filter.secondaries, for obvious reasons.
gl.filter.overshoot(x, save2tmp = FALSE, verbose = NULL)A new genlight object with the recalcitrant loci deleted
Name of the genlight object [required].
If TRUE, saves any ggplots and listings to the session temporary directory (tempdir) [default FALSE].
Verbosity: 0, silent or fatal errors; 1, begin and end; 2, progress log ; 3, progress and results summary; 5, full report [default 2, unless specified using gl.set.verbosity].
