the circos.conf is here:

  3 <image>
  4 <<include etc/image.conf>>
  5 </image>

  7 karyotype=karyotype.txt
  8 chromosomes_units=100000
  9 chromosomes_display_default=yes
 10 
 11 <ideogram>
 12 <spacing>
 13 defalut=0.005r
 14 </spacing>
 15 radius=0.80r
 16 thickness=6p
 17 fill=yes
 18 fill_color=deepskyblue
 19 stroke_color=black

 23 label_radius=30
 24 label_size=30
 25 label_parallel=yes
 26 </ideogram>

 28 <<include etc/housekeeping.conf>>

and here is the plot data:

  1 chr - scaffold1 1 0 1102171 deepskyblue
  2 chr - scaffold2 2 0 2826618 red

Is the karyotype.txt file the same genome and range of chromosomes as your input data?
