+The Base Position feature in the Genome Browser annotations track image shows +the genomic coordinates of the displayed region and -- when zoomed in to the +base level -- the base composition of the sequence underlying the annotation +tracks display. To quickly zoom in to the base level, click the base +zoom-in button. The base button may also be used to automatically +zoom the window to maximize the base display when the image is resized. Click +the arrow to the left of the base display to show the base complement. +To toggle between dense and full display mode, click anywhere on the base +composition line.
++In dense display mode, clicking anywhere on the genome coordinate line will +zoom-in the display, centered on the coordinate of the click. The degree of +the zoom may be configured through the Zoom configuration buttons (the default +is 3X). In full display mode, the track shows three frames of translation +when viewed at the base level. Methionines (including potential start codons) +are displayed in green and labeled "M". Stop codons are colored +red and labeled with "*". Codons within or on the boundaries of +gaps, or at the ends of the chromosome, are colored black and labeled +with an "X" to indicate an +error (e.g. a truncated codon). All other codons are shown in alternating +shades of gray to indicate codon boundaries and are labeled by the amino +acids they represent. To view the translation on the reverse strand, click +the arrow to complement the base display.
++To add a title to the top of the display browser display image, enter the text in +the Title textbox. To display the name and date of the assembly, check +the Assembly checkbox. To display the position and chromosome, check +the Position checkbox.
