Killed on using modification on same amino acid and not able to apply more than 4 variable modification

[mansi123-rana]

Hi,

I am trying to use sage for different modification, but it does not work

example for apply modification;

"variable_mods": {
"M": [15.9949],
"S": [79.9663],
"K": [14.0156],
"K": [42.0469],
"T": [79.9663]
},

so please let me know how to use multiple modification on same amino acid.

Thanks,

You need to use "K": [14.0156, 42.0469].
