This section provides a brief description of the columns in custom track management table. For more details about managing custom tracks, see the Genome Browser User's Guide.

• Name - a hyperlink to the update page where you can edit your track data.
• Description - the value of the "description" attribute from the track line, if present. If no description is included in the input file, this field contains the track name.
• Type - the track type, determined by the Browser based on the format of the data.
• Doc - displays "Y" (Yes) if a description page has been uploaded for the track; otherwise the field is blank.
• Items - the number of data items in the custom track file. An item count is not displayed for tracks lacking individual items (e.g. wiggle format data).
• Pos - the default chromosomal position defined by the track file in either the browser line "position" attribute or the first data line. Clicking this link opens the Genome Browser or Table Browser at the specified position (note: only the chromosome name is shown in this column). The Pos column remains blank if the track lacks individual items (e.g. wiggle format data) and the browser line "position" attribute hasn't been set.
