-a,--annotate Search PuChem for each product, and annotate with CID and synonyms
-b,--btType The type of description: Type of biotransformer - EC-based (ecbased), CYP450 (cyp450), Phase II (phaseII), Human gut microbial (hgut), human super transformer** (superbio, or allHuman), Environmental microbial (envimicro)*.
-h,--help Prints the usage.
-ismi, --ismiles Read the input as a single molecule in SMILES format
-imol, --molinput Read the input as a single molecule in the specified MOL format
-isdf, --sdfinput Read the input from the specified SDF format
-k, --task The task to be permed: pred for prediction, or cid for compound identification
-m,--mList Given the starting comound(s), Find all their metabolites with the specified masses, and show a metabolism pathway. A whitespace-separated list of masses is expected.
-ocsv, --csvoutput Save the results into the specified CSV file
-osdf, --sdfoutput Save the results into the specified SDF file
-f,--formulas Semicolon-separated list of formulas
of compounds to identify
-s,--nsteps The number of steps for the
prediction. This option can be set by
the user for the EC-based, CYP450,
Phase II, and Environmental microbial
biotransformers. The default value is 1.
-t,--mTolerance Mass tolerance for metabolite
identification (default is 0.01).
(* ) While the 'superbio' option runs a set number of transformation steps in a
pre-defined order (e.g. deconjugation first, then Oxidation/reduction,
etc.), the 'allHuman' option predicts all possible metabolites from any
applicable reaction(Oxidation, reduction, (de-)conjugation) at each step.
(** ) For the environmental microbial biodegradation, all reactions (aerobic and anaerobic) are reported, and not only the aerobic biotransformations (as per default in the EAWAG BBD/PPS system).
Examples:
-
To predict the biotransformation of a molecule from an SDF input using the human super transformer (option superbio) and annotate the metabolites with names and database IDs (from PubChem), run
java -jar biotransformer-1-0-8.jar -k pred -b superbio -isdf -i #{input file name} -osdf #{output file} -a.
-
To predict the 2-step biotransformation of Thymol (a monoterpene) using the human super transformer (option allHuman) using the SMILES input and saving to a CSV file, run
java -jar biotransformer-1-0-8.jar -k pred -b allHuman -ismi "CC(C)C1=CC=C(C)C=C1O" -ocsv #{replace with output file name} -s 2
Currently, the outputfile is SDF per default.
-
Identify all human metabolites (max depth = 2) of Epicatechin ("O[C@@H]1CC2=C(O)C=C(O)C=C2O[C@@H]1C1=CC=C(O)C(O)=C1") with masses 292.0946 Da and 304.0946 Da, with a mass tolerance of 0.01 Da. Provide an annotation (Common name, synonyms, and PubChem CID), when available.
java -jar biotransformer-1-0-8.jar -k cid -b allHuman -ismi "O[C@@H]1CC2=C(O)C=C(O)C=C2O[C@@H]1C1=CC=C(O)C(O)=C1" -osdf #{replace with output file name} -s 2 -m "292.0946;304.0946" -t 0.01 -a
- DO NOT forget the quotes around the SMILES string or the list of masses.
