tuple index out of range

[kangdong318]

Hi Developers!
I'm running multiple lesions of a patient through PhylogicNDT. But I meet bug when I running "PhylogicNDT.py Cluster -i test -sif test_4.txt --maf_input_type calc_ccf --use_indels -rb". The test_4.txt includes the following:
sample_id maf_fn seg_fn purity timepoint
sample1 sample1.txt 0.1 1
sample2 sample2.txt 0.1 2
sample3 sample3.txt 0.1 3
It's normal to run sample1 and sample2, but I meet bug when run sample3 ,following(I removed some unimportant information):
File "PhylogicNDT.py", line 515, in
args.func(args)
File "Cluster.py", line 86, in run_tool
mode="maxpear", seed=args.seed)
File "ClusterEngine.py", line 43, in run_DP_ND
nd_hist = self. patient._make_ND_histogram()
File "Patient.py", line 316, in _make_ND_histogram
return NDHistogram(combined_ccf, [x.var_str for x in self.sample_list[0].concordant_variants])
File "Patient.py", line 671, in init
n_samples = np.shape(hist)[1]
IndexError: tuple index out of range.
But is more strange that when I run sample3 lonely, it's normal to get output.
Are there any strategies that can help me resolve the bug? Thank you.
sincerely,
KangDong
