Collection of models used in the introduction of absolute units into A. thaliana circadian clock models, with software resources and documentation. The models are inspired by P2011, published in Pokhilko et al 2012. The study contains Assays that link to the P2011 starting model and the models U2019.1  .3 and U2020.1  .3. Each model is shared as a humanreadable file in the Antimony language and the associated, machinereadable SBML file, which was automatically generated using the SBML export routine of Tellurium software. The full computational environment for parameter fitting, using custom costing in SloppyCell, is shared as a Docker image. SBML files were verified using COPASI 4.24 (Build 197) software. The full process is described in Urquiza and Millar, In Silico Plants, 2021. The publication will be linked to the live version of this Investigation but cannot be linked to the Snapshot as no DOI had been assigned when the Snapshot DOI had to be generated.

The dataset presents mathematical models of the gene regulatory network of the circadian clock, in the plant Arabidopsis thaliana. The work is published in UrquizaGarcia and Millar, Testing the inferred transcription rates of a dynamic, gene network model in absolute units, In Silico Plants, 2021.
Starting from the P2011 model, this project corrects theoretical issues (EC steady state binding assumption) to form an intermediate model (first version U2017.1; published as U2019.1) model, rescales ...

This section contains the links to the tools used for reproducing the computational results presented in U2019. This is required because SloppyCell is under the risk of becoming rotting code. Using Docker we can assure some persistence for the computational environment that allows to run SloppyCell.
The associated git repository can be found in https://github.com/jurquiza/Urquiza2019a.git which can be cloned.
The docker image can either be pulled from the docker hub site

Collection of clock models that rescale transcript variables to account for absolute units. The relationship between models is summarised in the attached 'model evolution' document and in more detail in the linked publications (preprint version linked in the Snapshot; publication Urquiza and Millar, In Silico Plants 2021 did not have a DOI when Snapshot was created).

Model derived from U2019.2, fitted to TiMet data mutants data set. Fixed parameters are scaling factors, COP1 and cP parameters. The rest of the parameters were left optimisable. The networks used in the fitting include WT, lhycca1, prr79, toc1, gi and ztl. The ztl network was only used for fixing the period in this mutant. Then final parameter values for transcription rated were obtained by taking the product of scaling factor and either transcription or translation, the latter required for ...

Model derived from U2019.1, in which the way the PRR genes are regulated is modified. Repression mechanism introduced Instead of activation between the PRRs for producing the wave of expression. This is inspired in the result of three models P2012, F2014 and F2016. P2012 introduced TOC1 repression in earlier genes relative to its expression. F2014 introduced also the backward repression of PRR9  PRR7  PRR5, TOC1. However little attention was given to why there is a sharper expression ...
