primeDTLSR - Guest-in-host tree inference tool
Contents
Description
Guest-in-host tree inference enabling reconciliation analysis using the underlying DTLRS model. Model
properties:
1) The guest tree topology evolves inside the host tree by means of duplication, loss and horizontal
transfer events guided by homogeneous rates, much like a birth-death process. Lineages branch
deterministically at host tree nodes.
2) Relaxed molecular clock; sequence evolution rate variation over guest tree edges. Rates are drawn
iid from specified distribution. Also, rate variation over sites may be added, using discretized
gamma distribution with mean 1.
3) Substitution model of choice; standard or user-defined. The implementation uses a discretization
of the host tree to approximate the probability of all possible reconciliation realizations for
the current parameter state.

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.Exit Status
0 Successful program execution.

Options
-h, -u, -?
Display help (this text).
-oFILE
Output filename. Defaults to stderr.
-sUNSIGNED_INT
Seed for pseudo-random number generator. Defaults to random seed.
-iUNSIGNED_INT
Number of iterations. Defaults to .
-tUNSIGNED_INT
Thinning, i.e. sample every <value>-th iteration. Defaults to .
-wUNSIGNED_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|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.
-SnUNSIGNED_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 rate variation among edges. Defaults to .
-EpFLOATFLOAT
Initial mean and variance of edge rate distribution. Defaults to and .
-Ef Fix mean and variance of edge rate distribution. Non-fixed by default.
-GiFILE
Filename with initial guest tree topology.
-Gg Fix initial guest tree topology, i.e. perform no branch-swapping. Non-fixed by default.
-BpFLOATFLOATFLOAT
Initial duplication, loss and transfer rates. Defaults to , and .
-Bf Fix duplication, loss and transfer rates to initial values. Non-fixed by default.
-BtFLOAT
Override time span of edge above root in host tree. Must be greater than 0. Defaults to file-
contained value.
-DtFLOAT
Approximate discretization timestep. Set to 0 to divide edge generations into the same amount of
parts (see -Di). Defaults to .
-DiUNSIGNED_INT
Minimum number of discretization subintervals per edge generation. If -Dt is set 0, this becomes
the exact number of subintervals. Minimum 2. @Defaults to conf_value_from_cmake_DiscMinIvs@.
-CUNSIGNED_INT
Number of transfer counts during sampling. Defaults to .
-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.
-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.
