Genome Browser BAM tracks may be configured in a variety of ways to
highlight different aspects of the displayed information. 
The configuration options are described here and related to custom track 
settings that can alter the default appearance of the custom track.

on BAM custom track creation.
 
Attempt to join paired end reads by name:
    This checkbox appears only if pairEndsByName is included in the
    track settings.  When checked, SAM/BAM records with the same name will be 
    joined into pairs for display, with a line drawn between them.Minimum alignment quality:
    Exclude alignments with quality less than the given number.  The default is 0,
    unless changed by the track setting minAliQual.Color track by bases:
    By default, mismatching bases are highlighted in the display.  
    Change the selection to "item bases" to see all base values from
    the query sequence, or "OFF" to ignore query sequence.Additional coloring modes:
    Other aspects of the alignments can be displayed in color or grayscale.
    The default mode is 'Color by strand' (bamColorMode=strand), unless
    the bamColorMode track setting specifies gray, tag
    or off.
    
    Color by strand:
        alignments on the reverse strand are colored dark red, alignments on the 
	forward strand are colored dark blue.Grayscale:
        items are shaded according to the chosen method:
        alignment quality, base qualities, or unpaired ends.
	Items' alignment qualities are shaded on a scale of 0 (lightest) to 99 (darkest).  
        Base qualities are shaded on a scale of 0 (lightest) to 40 (darkest).
	When "unpaired ends" is selected, items that were paired in sequencing
	but whose mate was not mapped are colored gray, while singletons and properly
	paired items are black.
	Alignment quality is the default (bamGrayMode=aliQual) unless
        bamGrayMode track setting is baseQual or unpaired.Use R,G,B colors specified in user-defined tag:
        SAM/BAM may include user-defined tags, whose names begin with X, Y or Z 
	and include one other letter or number.  The user-defined tag named here
	specifies red, green and blue (RGB) intensities	as a zero-terminated string
	(tag type Z) containing comma-separated triples
	of numbers from 0-255.  For example, if a SAM/BAM record includes the tag
        YC:Z:255,0,0, then the item is colored red;  
	YC:Z:0,0,255 makes the item blue.
	By default, the tag is "YC" unless changed using the track setting
	bamColorTag.No additional coloring
