Description

create_batch_body returns a string of a POST request body.

Usage

create_batch_body(metabolites_type = "all-except-peptides",
  databases = "[\"all-except-mine\"]", masses_mode = "mz",
  ion_mode = "positive", adducts = "[\"M+H\",\"M+Na\"]",
  tolerance = 10, tolerance_mode = "ppm", unique_mz)

adducts

for positive mode [M+H, M+2H, M+Na, M+K,M+NH4, M+H-H2O]

tolerance

double (Range: [0..100])
