# Probe match (Expert) OCCURRENCE DESCRIPTION NOTES EXAMPLES WARNINGS BUGS ## OCCURRENCE
### ARB_NT/Probes/Match Probes/EXPERT
## DESCRIPTION
### See ´Strength of base pairings´ for upper area. ### Define how many N-matches are accepted: 'Accepted N-matches' defines the amount of N-matches that are accepted wothout causing a mismatch. 'N-match limit' defines an upper limit for N-matches. Whenever that limit is reached inside one probe, all N-matches count as mismatches. ### Define max. results: The number of hits is limited to 1 million by default. This is just there to protect you from waiting several hours for match results, just because your settings were too lax. Changing it to 0 disables the limitation.
## NOTES
### An N-Match is caused either by Ns in the matched probe or by Ns in the hit target region.
## EXAMPLES
### None
## WARNINGS
### Specifying high values for N-matches and then matching a probe containing many Ns, may keep your machine busy for days. Use with care.
## BUGS
### No bugs known
