KB000182: What Does Error ''X-axis is not equidistant'' Indicate? - LC/MS ChemStation 

The error "X-axis is not equidistant" can occur when an MSD TIC is integrated if the method is configured to use the old ChemStation (Genie) integrator. The LC/MSD ChemStation does not support the old ChemStation integrator--it only supports the use of the new Enhanced integrator. However, an LC/MSD method might be configured to use the old ChemStation integrator if a rev. A.04.xx LC ChemStation method was loaded and updated for use with the LC/MSD ChemStation, or if the method hpchem\1\methods\defoldlc.m was used to create an LC/MSD method. To correct the problem, you need to recreate the method using the default method \hpchem\1\methods\def_lc.m as a template.
