Simple M/z input
File type
Plain text. (Save Excel files as ‘Tab Delimited Text’.)
Identifier Line
The first line should consist of a zero (‘0’) preceded by a character indicating the mode: ‘P’ for positive mode, ‘N’ for negative mode, or ‘U’ for neutral mode (i.e. positive or negative mode masses corrected for one proton).
Data Lines
Each data line should contain a single M/z value.
Example
An example file, ‘simplemz.txt’ can be found in the folder of examples (in ‘Downloads’). The first few lines are as follows:
P0 199.1692421 199.1691189 384.1444594 314.2690337 241.0707449 259.0924694
The ‘P’ at the start of the identifier line indicates that the data are from an analysis run in positive mode.
