PROGRAM:
NAME
primeDLRS, primeGSRf - Guest-in-host tree reconciliation tool
SYNOPSIS
primeDLRS [OPTIONS] seqfile hostfile [gsfile]
DESCRIPTION
Guest-in-host tree reconciliation tool, enabling analysis of e.g. guest tree topologies,
reconciliation properties and duplication-loss rates. Based on a Bayesian MCMC framework
using the underlying GSR model. The old program name, primeGSRf, is still available as a
symlink to primeDLRS.
1) the guest tree topology and its divergence times are modelled with a duplication-
loss process in accordance with the Gene Evolution Model (GEM).
2) sequence evolution is modelled with a user-defined substitution model.
3) sequence evolution rate variation over guest tree edges (relaxed molecular clock)
are modelled with iid values from a user-selected distribution.
4) sequence evolution rate variation over sites (positions) are modelled according to
a discretized Gamma distribution.
The implementation uses a discretization of the host tree to perform its computations.
Please review available options, as you will need to change default settings. Option -r
may be useful to avoid numeric issues due to scaling.
seqfile is a file with aligned sequences for guest tree leaves.
hostfile is a PrIME Newick file with host tree incl. divergence times. Leaves must have
time 0 and root have time > 0.
gsfile is a tab-delimited file relating guest tree leaves to host tree leaves if info not
included in hostfile.
OPTIONS
-h, -u, -?
Display help (this text).
-o FILE
Output filename. Defaults to stderr.
-s UNSIGNED_INT
Seed for pseudo-random number generator. Defaults to random seed.
-i UNSIGNED_INT
Number of iterations. Defaults to .
-t UNSIGNED_INT
Thinning, i.e. sample every <value>-th iteration. Defaults to .
-w UNSIGNED_INT
Output diagnostics to stderr every <value>-th sample. Defaults to .
-q Do not output diagnostics. Non-quiet by default.
-m MCMC|PDHC|PD
Execution type (MCMC, posterior density hill-climbing from initial values, or just
initial posterior density). Defaults to .
-Sm UniformAA|JC69|F81|JTT|UniformCodon|ArveCodon
Substitution model. by default.
-Su DNA|AminoAcid|Codon <Pi=float1 float2 ... floatn> <R=float1 float2
...float(n*(n-1)/2)>
User-defined substitution model. The size of Pi and R must fit data type (DNA: n=4,
AminoAcid: n=20, Codon: n=62). R is given as a flattened upper triangular matrix.
Don't use both option -Su and -Sm.
-Sn UNSIGNED_INT
Number of steps of discretized Gamma-distribution for sequence evolution rate
variation over sites. Defaults to (no variation).
-Ed Gamma|InvG|LogN|Uniform
Distribution for iid sequence evolution rate variation over guest tree edges.
Defaults to (not to confuse with -Sn).
-Ep FLOAT FLOAT
Initial mean and variance of sequence evolution rate. Defaults to simple rule-of-
thumb based on host tree times.
-Ef Fix mean and variance of sequence evolution rate. Non-fixed by default.
-Gi FILE
Filename with initial guest tree topology.
-Gg Fix initial guest tree topology, i.e. perform no branch-swapping. Non-fixed by
default.
-Gl Fix initial guest tree edge lengths (in addition to topology), i.e. fix the edge
lengths. Non-fixed by default.
-Bp FLOAT FLOAT
Initial duplication and loss rates. Defaults to and .
-Bf Fix initial duplication and loss rates. Non-fixed by default.
-Bt FLOAT
Override time span of edge above root in host tree. If the value is <=0, the span
will be set to equal the root-to-leaf time. Defaults to value in host tree file.
See also option -Dtt.
-Dt FLOAT
Approximate discretization timestep. Set to 0 to divide every edge in equally many
parts (see -Di). Defaults to . See -Dtt for edge above root.
-Di UNSIGNED_INT
Minimum number of parts to slice each edge in. If -Dt is set to 0, this becomes the
exact number of parts. Minimum 2. Defaults to . See -Dtt for edge above root.
-Dtt UNSIGNED_INT
Override number of discretization points for edge above root in host tree. By
default, irrespective of time span, this is set to the number of points for a
(hypothetical) root-to-leaf edge
-r Rescale the host tree so that the root-to-leaf time equals 1.0. All inferred
parameters will refer to the new scale. Off by default. Note that discretization
parameters are NOT rescaled.
-Z Do not print elapsed wall time and CPU time
-W Do not print the command line
-debuginfo
Show misc. info to stderr before iterating. Not shown by default.
EXIT STATUS
0 Successful program execution.
1 Some error occurred
