kinwalker

Model cotranscriptional RNA folding while the chain is still elongating.
Compare different barrier heuristics for transient folding pathways.
Tune transcription rate and folding window size to match a biological regime.
Produce a trajectory-oriented kinetics prediction rather than an equilibrium ensemble.

# 1) Run a basic cotranscriptional folding simulation
kinwalker < seq.txt > trajectory.txt

# 2) Change the barrier heuristic and transcription rate
kinwalker --barrier_heuristic B --transcription_rate 50 < seq.txt > trajectory.txt

# 3) Constrain the folding window and disable lonely pairs
kinwalker --windowsize 120 --nolonely 1 < seq.txt > trajectory.txt

Prepare sequence input file with target RNA sequence
Select barrier heuristic via --barrier_heuristic (M/S/B/A; default: M for Morgan-Higgs)
Set transcription parameters (--transcription_rate, --transcribed, --windowsize) to match biological conditions
Run kinwalker, redirect output to file, and review predicted folding trajectory

Does not support --version; use --help to verify installation
Input read from SeqFile or stdin; output written to Outfile or stdout
ViennaRNA parameters (--dangle, --nolonely) should be consistent with any upstream/downstream ViennaRNA tools
