Welcome to FindSim
FindSim project involves following broad sections:
Open Neuronal Signaling Consortium seeks to develop data-driven, rigorously parameterized models of neuronal signaling across scales, in health and disease, and in a range of systems.
The Signaling And Neurophysiology Knowledge-resource for Experiments and Theory (SANKET) seeks to develop data-driven, rigorously parameterized models of neuronal signaling across scales, in health and disease, and in a range of systems. The data, models, and tools are open so as to serve as a community resource for research, teaching, and translation.

B: FindSimInterface Link: http://findsim.ncbs.res.in/findsiminterface/ FindSimInterface, provides maps models of neural and cellular signaling to experimental protocols and readouts. It runs the experiment on the model, and provides a score that reports how closely the two match.

registered email.
Click on the link and change the password.
Menu Bar
The menu bar appears at the top of the main window.
The Home menu otion provides general information about FindSim interface.
The ExpModmap menu option provides the following sub options
a) ExpModmap: Experiment Model Mapping List
This list shows title of experiment performed, cells types used in experiment, type of experiment (Dose response, Time series, Bar Chart or Direct Parameters) and species used for generation of experimental data.
b) Non curated Models
The following models are not part of the curated branch of FindSim interface. While the syntax of the models has been verified, their semantics remains unchecked. We are doing our best to incorporate these models into the main curated branch as soon as possible.
c) Upload models
We can create, uplaod or download TSV file by
using this option
In generation of new FindSim experiment this menu is used.
Create FindSim form
Title of experiment to be performed
Project: You can add name of project or disease for which model has been generated.
By using create FindSim Form; we will perform new
FindSim experiment.
Experimental details
It consists of five parts
1. Experimental Metadata
Scientific data are generated by experiments or observations. In order to be interpreted, or even accessed, they must be accompanied by auxiliary information, ranging perhaps from the experimenter, year of publication, name of journal and place that the experiment was conducted to arcane calibration details. This auxiliary information constitutes the metadata for the experiment. Notably it is likely to be more extensive and less standardised.
Considerable effort must be made to capture all this information if the data are to be retained for posterity or made available to a wider community of users.
For example:
Transcriber: A Transcriber transliterates whenever possible the original model format into the tsv format for FindSim interface.
Organization: National Centre for Biological Sciences
Experiment Source: In this tab you have to select source of experimental data.
Experimental Source has three options a) Paper b) Inhouse c) Experiment
Citation ID: Foreign key identifier of the citation being extended; For Exaple: PMID: 10486198
Email: vinod.ugale@rediffmail.com
Authors: Eric C. Yuen and William C. Mobley
Journal: Experimental Neurology
2. Experimental Contexts
a) Experiment Type: This list shows title of experiment performed, cells types used in experiment, type of experiment (Dose response, Time series, Bar Chart or Direct Parameters), and species used for genration of experimental data and temperature ("C).
Include pathways: Pathways included in experiment
For example: BDNF,TrKB,PLCg
Notes: Any additonal information about experiment; For example: Replication of results of Pragati's paper
3. Model Mapping
A mapping model contains the information that defines the relationships between the source and target data that you specified, including experimental conditions, pathways invloved, items to delete, and annotations.
In model mapping you will find these different sections:
1. Model Source: It can be a local path, DOCQS (Database of Quantitative Cellular Signaling; https://doqcs.ncbs.res.in/) or Biomodels (BioModels Database is a repository of computational models of biological processes; https://www.ebi.ac.uk/biomodels/).
2. File Name: We have to select appropriate model which involves subset for experimental data.
In this section we have to fill auxiliary information constitutes the metadata for the experiment.
3. Scoring Formula: Add the formula as: abs((expt-sim)/(expt+sim+1e-9))
4. Solver: It includes different methods of numerical analysis such as Runge–Kutta methods; stochastic simulation; Exponential Euler Method.
5. Model Subset: Select the set of group for which experiment has been performed. For example: kinetics/BDNF,kinetics/TrKB,kinetics/PLC_g.
6. Model Lookup: Write a Pathways which is taken into consideration; For example: BDNF:BDNF/BDNF,pPLCg:PLC_g_p.
7. Parameter change: Select appropriate parameter such as Conclnit, nlint, Kf, Km, Kcat, Kb, etc. Add value for selected parameter.

ModelSource
DOQCS: The Database of Quantitative Cellular Signaling is a repository of models of signaling pathways. It includes reaction schemes, concentrations, rate constants, as well as annotations on the models. The database provides a range of search, navigation, and comparison functions.
BioModels: It is a repository of mathematical models of biological and biomedical systems. It hosts a vast selection of existing literature-based physiologically and pharmaceutically relevant mechanistic models in standard formats. Our mission is to provide the systems modelling community with reproducible, high-quality, freely-accessible models published in the scientific literature.
Runge–Kutta methods
In numerical analysis, the Runge–Kutta methods are a family of implicit and explicit iterative methods, which include the well-known routine called the Euler Method, used in temporal discretization for the approximate solutions of ordinary differential equations. These methods were developed around 1900 by the German mathematicians Carl Runge and Wilhelm Kutta.
