If your CPU has multiple cores and OpenMP is detected, the calculation will execute in parallel and the number of available threads appears in the GUI title bar. Gradients are not required, however, they are recommended as they have been shown to\u00a0help docking find solutions more efficiently. The addition of gradients requires the definition of the <em>interior<\/em> and <em>exterior<\/em> of the receptor. By default, the largest cluster of negative values (favorable affinities) is used to define the exterior of the receptor. In this case, everything else, including receptor cavities large enough to hold solvent but not open to the solvent, will be considered the interior and will be overwritten with the gradient. To prevent the gradient generation on grid points of internal cavities, the user can specify a cluster size above which clusters of points with negative values are considered to be outside the receptor and therefore preserve their original affinity values.<\/p>\n<\/div><div class=\"nav fusion-mobile-tab-nav\"><ul class=\"nav-tabs\" role=\"tablist\"><li role=\"presentation\"><a class=\"tab-link\" data-toggle=\"tab\" role=\"tab\" aria-controls=\"tab-4d7154e8e96ecbd48cb\" aria-selected=\"false\" tabindex=\"-1\" id=\"mobile-fusion-tab-generatemaps\" href=\"#tab-4d7154e8e96ecbd48cb\"><h4 class=\"fusion-tab-heading\"><i class=\"fontawesome-icon fa-calculator fas\" aria-hidden=\"true\" style=\"font-size:13px;\"><\/i>Generate maps<\/h4><\/a><\/li><\/ul><\/div><div class=\"tab-pane fade fusion-clearfix\" role=\"tabpanel\" tabindex=\"0\" aria-labelledby=\"fusion-tab-generatemaps\" id=\"tab-4d7154e8e96ecbd48cb\">\n<h4><span style=\"color: #008080;\">Click on the \u201cgenerate target file\u2026\u201d button\u00a0<\/span><\/h4>\n<div class=\"fusion-sep-clear\"><\/div><div class=\"fusion-separator fusion-full-width-sep\" style=\"margin-left: auto;margin-right: auto;margin-top:15px;margin-bottom:15px;width:100%;\"><div class=\"fusion-separator-border sep-double sep-solid\" style=\"--awb-height:20px;--awb-amount:20px;border-color:#e0dede;border-top-width:1px;border-bottom-width:1px;\"><\/div><\/div><div class=\"fusion-sep-clear\"><\/div>\n<p>Details: the program asks for the name and location for the target file that will be generated.
