CoRAL plot error

[ucsfpan]

Hi author,
Thanks for this great tool. I have run the command:
/c4/home/ucsf-pan/software/CoRAL/src/CoRAL.py seed --cn_seg /bastianlab/data1/hpan/pacbio_ccs/CNVkit_m84127/m84127.mini.pacbioccs.cns
/c4/home/ucsf-pan/software/CoRAL/src/CoRAL.py reconstruct --lr_bam /bastianlab/data1/hpan/pacbio_ccs/alignment_mini/m84127.mini.pacbioccs.bam --cnv_seed /bastianlab/data1/hpan/pacbio_ccs/CNVkit_m84127/m84127.mini.pacbioccs_CNV_SEEDS.bed --output_prefix samp1 --cn_seg /bastianlab/data1/hpan/pacbio_ccs/CNVkit_m84127/m84127.mini.pacbioccs.cns
/c4/home/ucsf-pan/software/CoRAL/src/CoRAL.py plot --ref GRCh38 --bam /bastianlab/data1/hpan/pacbio_ccs/alignment_mini/m84127.mini.pacbioccs.bam --graph amplicon1_graph.txt --cycles amplicon1_cycles.txt --output_prefix aa --plot_graph --plot_cycles

The first two steps are successful, and I got the output GRCh38_CNV_SEEDS.bed Graph file Cycles file, but when I try to plot , it come out of such issue. Would you please help me to solve this? Thanks!
