Instructions and Help

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.
