WEB CONSULTATION INTERFACE
==========================

Query forms
-----------

Each crop module has several interfaces to carry out specific requests. The interfaces are tab-based, with each tab containing a different query form that leads to different types of data: phenotypes, genotypes, passport data, markers, QTLs, etc. A query form consists of various kinds of filters represented by standard input widgets. An important point is the ability to select the operator (AND/OR) applied for grouping together the filters defined by the used widgets. Filters corresponding to numerical values can be combined using relational operators (more than, equal to, etc.). For mapping data, users can filter on mapped markers and QTLs inside or overlapping a segment of given left and right limits (bp or cM) ([Figure 1](#gks1105-F1){ref-type="fig"}A).

Some text boxes have lookup lists tied to them. This is particularly useful when a non-trivial, exact string is expected. Filters where a red cross lies between the criterion label and the widget can be removed by clicking on the indicated cross icon. Those filters can also be (re-)added, several times if needed, using the 'Add criterion' list box. Having several identical filters only makes sense when using the OR operator because otherwise selecting two different values for the same criterion would result in an empty data set.

Filters for which no red cross appears primarily consist of list boxes whose contents are subject to a dependency relationship. This kind of relationship ties list boxes two by two: the contents of the second one are automatically updated when sele
