I'm working in mass spectrometer data with an extension (.mzxml) and I'm able to read the file using (mzxmlread) command. The problem, when I read the same file with another software that used for re-processing mass spectrometer data OpenMZ "TOPPView" and save the file with the same extension (mzxml) when I try to read the file in Matlab, the error message appears which is: {
??? Error using ==> numel Bad subscripting index.
Error in ==> mzxmlread at 222 count2 = numel(out.mzXML.msRun.(elementName).(childElemNm)); }
if there is any help that will be really appreciated. Khalf

Given the line of code
numel(out.mzXML.msRun.(elementName).(childElemNm));
I expect elementName and chilElemNm to be strings, as they are used to access fields within the out.mzXML.msRun structure.

Dear Khalfalla,
The problem might be that your mzxml file that you create is too new/advanced for MATLAB to read using 'mzxmlread'.
The function ' mzxmlread' reads mzXML files that are conform to the mzXML 2.1 specification or earlier specifications. Use an older version of your mzxml processing software and try again!
