Cannot open or see all functions in MassLynx data files - WKB46637

SYMPTOMS

• The MS MRM Method contains numerous functions but only the earlier functions are showing. The later MRM functions are missing.
• After acquiring raw data, all functions are present in the data file and listed in the Experiment record, but only the first functions can be opened in MassLynx  (e.g. up to function 22, 23, 24 etc)
• Not all the functions are listed in the function drop-down list in the Chromatogram Data Browser, so they cannot be opened
  e.g. Here there are more than 23 Functions but only Functions 1-23 can be viewed and the scroll bar will not scroll further down (there may not be a scroll bar visible depending on the functions)
• 
• This is embedded in the data file and is seen irrespective of the MassLynx version the data is viewed on.

ENVIRONMENT

• MassLynx
• Xevo TQ Absolute
• Xevo TQ-GC
• Xevo TQ-XS
• Xevo TQ-S micro 
• Xevo TQ-S cronos
• Xevo TQD
• Xevo TQ-S
   

CAUSE

The compound name used for the last shown is too long. 

There is a length limit of 55 characters in the MassLynx MS Method Editor. The name attempted has 56 or more characters and this stops this function from displaying.
For example: Function 22 compound is called ("Benzo(a)pyrene d12+ Benzo(b) et Benzo(k)fluoranthene d12")
Some compound names created in QuanOptimise have extra detail - e.g. [Demo 5V] adding more characters to the length

FIX or WORKAROUND

Rename the compounds so they have fewer than 56 characters (including spaces),

Reprocess the data.
