From TNT
XMULT
Version: 1.1.
Menu path: to do.
Xmult Run multiple replications, using sectorial searches, drifting, ratchet and fusing combined. Options are set with "xmult:options;" or "xmult=options;" (using ":" only settings are changed; "=" runs as well). With "xmult:;" current settings are displayed. If consensing, / followed by a taxon list removes the specified taxa from the consensus (this must follow all the other options). If css, rss, and xss are specified css is done first, then rss, and xss last.
Options are:
hits N produce N hits to best length and stop
replications N for each hit, search initially with N replications
[no]targetscore N search until score N found (only with fusing)
[no]update do not update targetscore
[no]giveupscore N give up search as soon as score N found
[no]rss use random sectorial searches (settings with
sectsch:options)
[no]css use constraint sectorial searches (settings with
sectsch:options)
[no]xss use exclusive sectorial searches (settings with
sectsch:options)
[no]fuse use fusing (settings with tfuse:options)
[no]gfuse N every N hits, fuse all trees (=score check)
[no]dumpfuse if fusing fails to produce trees of target score,
dump the trees produced by fusing (may prevent
"clogging" of subsequent fuses by keeping only the
most distinct trees)
[no]drift N use N cycles of drifting (settings with drif:options)
[no]ratchet N use N cycles of ratchet (settings with rat:options)
[no]autoconst N use consensus of previous run and initial stages of
current as constraint for initial stages. 1=previous
and wagner, 2=previous and SPR, 3=previous and TBR.
The first replication of a new hit is never
constrained (i.e. hits are totally independent).
Note that level=2 defaults to 1 when "skipspr"
is on.
[no]xmix after unsuccesful fusing, start a new set of
replications as autoconstrained (otherwise, don't)
[no]prvmix if trees existed in memory before running xmult, use
last one to autoconstrain first xmult replication
[no]consense N consense untill consensus is stabilized N times
conbase N base hits to check for consensus stabilizations
(larger numbers make more reliable estimations)
confactor N factor to increase number of hits to check consensus
stabilization (10-100, larger numbers: more reliable)
conmax N maximum new hits to recheck consensus (default=12)
[no]keepall keep trees from all replications
[no]retouch N before trying new replications, repeat sectorial
search and ratchet/drifting
level N set level of search (0-10). Use 0-2 for easy data
sets, 2-5 for medium, above 5 for difficult
chklevel N check search parameters during run, every N hits.
The parameters are increased or decreased, starting
from user settings. If N is preceded by +F (between
0 and 2), the entire level is changed by F. If N is
preceded by -, user settings are starting point
[no]multiply after hitting target score, find additional trees
by fusing suboptimal with optimal trees
[no]verbose produce verbose reports
Example: run an analysis using new technologies.
xmult=rss fuse 2 drift 3 ratchet 10;
TNT will perform random sectorial searches, fuse (2 cycles), drifting (3 cycles) and ratchet (10 cycles) in your search.
