Hits Report Table Features

The Hits Report table typically contains many items, so it may be useful to use filtering and/or sorting to simplify finding the interesting cases. Some columns also contain links to additional information for the respective item.

Selecting visible colums

The Hits report contains many columns, most of them are hidden by default. Press the column symbol next to Hit in the table header and a window will open up where you can select which columns to show.

Filtering Columns

Below the table header row is a filter row displaying active filter settings for the columns. Filtering can only be applied to columns corresponding to simple attributes in the database, which is indicated by the mouse cursor changing to a hand pointer when placed over the filter cell. Clicking on such a filter cell changes the view to one for selecting a filter setting for the column. Filtering can be applied to several columns at the same time. Initially, all filters are off.

A filter setting is composed of a condition and a value. The filter condition can normally be selected as one of "=" (equals), "!=" (not equal to), "<" (less than), "<=" (less or equal), ">" (greater than), and ">=" (greater or equal). The filter value is the right-side value in the comparison, i.e. a filter with condition "<" and filter value "0.5" selects only those items where the value in the column corresponding to the filter is < 0.5. When comparisons are made against a filter value, the variable type represented in a column should be considered, e.g. for integers 2 < 10, while for strings compared alphabetically "10" < "2". When a filter is active, all items with value null in the filtered column will be discarded. When a filter setting has been selected, it will be displayed in the cell for the column in the filter row.

Strings can be filtered using wild cards (% or *). For example, applying the condition "=" and the filter value "Masco%" to the score type column would show entries which have either of the score types "Mascot protein score" or "Mascot peptide score". Filtering the External Id column with the filter value "%22684%" would show all lines where 22684 can be found within the accession number. Note that wild card filtering only works for the "=" condition.

Sorting Columns

The Hits Report table can be sorted by one or more columns. To select which columns to sort by, press the column symbol next to Hit in the table header, and a window will open up where you can select columns to sort by.

A default sorting is applied, in order for the initial table to display items of probable interest.

Some columns have clickable links to their items, currently "Gel", "Spectrum", "Score", and "External Id". This is indicated by the the value in the cell being of different colour, and the mouse cursor changing to a hand pointer when placed over the cell. The action taken when clicking on such a cell depends on the column:

  • Clicking on a Gel item changes to the Gel view for the item if present in the database, otherwise it changes to a view for adding a Gel item with the specific Gel id.
  • Clicking on a Spectrum item changes to a view displaying the spectrum and related data.
  • Clicking on a Score item changes to a view displaying data for the selected Hit (this is the same information as that in the corresponding row in the Hits Report table, but displayed in a different format).
  • Clicking on an External Id generates a directed web search for data for the selected external id. Note that the information displayed is not taken from the Proteios database. The page may contain other web links that may be followed, but these are also outside Proteios.
  • Clicking on a combined FDR will show the peptide or protein search results which have been combined.
