47 What it does
|
|
|
48 -------------

|
|

|
|
|
50 This tool computes Reaction Propensity Scores based on the availability of reaction substrates, for (ideally) each input model reaction and for each sample.
|
|
|
51 The score is computed as the product of the concentrations of the reacting substances, with each concentration raised to a power equal to its stoichiometric coefficient. According to themass action law, the rate of any chemical reaction is indeed proportional to this product.
|
|
|
52 This assumption holds as long as the substrate is in significant excess over the enzyme constant KM.
|
|
|
53 If a metabolite is either missing in the model provided with respect to its reactions or it is present in our "black list", the RPS score is set to NaN.
|
|
|
54 This "black list" of metabolites contains those substrates that are present in too many reactions to be significant. It is defined in the file black_list.pickle and cannot be modified by the user.
|
|
|
55
|
|
|
56 Accepted files:
|
|
|
57 - An abundance dataset: Tab-separated text file reporting the abundance value of each metabolite for each cell line in the dataset.
|
|
|
58 Column header: cell line ID.
|
|
|
59 Row header: metabolite ID.
|
|
|
60
|
|
|
61
|
|
|
62 Optional files:
|
|
|
63 - Custom reaction dataset: .csv file specifying for each reaction ID the corresponding formula.
|
|
|
64 First column: reaction ID
|
|
|
65 Second column: reaction formula.

|

|
|
|
71 The tool generates:
|
|
|
72 - a tab-separated file(.csv): reporting the RPS values for each reaction and each cell line in the dataset.
|
|
|
73 - a log file (.txt).
