     readSpotTypes(file="SpotTypes.txt",path=NULL,sep="\t",check.names=FALSE,...)

_A_r_g_u_m_e_n_t_s:

    file: character string giving the name of the file specifying the
          spot types.

     and the following columns: 'SpotType' gives the name for the spot

     is a regular expression matching the Name column, and 'Color' is
     the R name for the color to be associated with this type.

_V_a_l_u_e:

     A data frame with columns 

SpotType: character vector giving names of the spot types

      ID: character vector giving regular expressions

    Name: character vector giving regular expressions

   Color: character vector giving names of colors
