The Peptide Isoforms page columns

Column

Description

Sequence

The peptide sequence.

Modifications

The modification composition of the peptide isoform group.

Modification Pattern

A string representation of the peptide highlighting the modification positions. Every amino acid in the peptide is represented by either a hyphen (-) or an asterisk (*), which indicate unmodified amino acids and modified amino acids, respectively.

If there is no possible site with a site localization probability above the threshold parameter given in the node parameter, this column reads not differentiable.

# Isoforms

The total number of isoforms found for this peptide mass and sequence.

# Protein Groups

The number of protein groups that contain the peptide sequence.

# Proteins

The number of proteins that contain the peptide sequence.

# PSMs

The number of PSMs that belong to the group.

# Missed Cleavages

The number of missed cleavages in the peptide.

Theo. MH+[Da]

The theoretical MH+ mass of the modified peptide, in daltons.

Confidence

The highest PSM confidence for the PSMs associated with the group.

Score columns

One or more score columns depending on the search nodes used in the processing workflow.
