Error in Generating consensus clonal evolution trees across samples

[qindan2008]

Hello,
When I run infer.clonal.models, an error occurred.

y = infer.clonal.models(variants = data,
cluster.col.name = 'cluster',
vaf.col.names = vaf.col.names,
ccf.col.names = ccf.col.names,
sample.groups = sample.groups,
cancer.initiation.model='monoclonal',
subclonal.test = 'bootstrap',
subclonal.test.model = 'non-parametric',
num.boots = 1000,
random.seed = 1234567,
founding.cluster = 1,
cluster.center = 'median',
ignore.clusters = c(2,3,4),
clone.colors = clone.colors,
min.cluster.vaf = NULL,
sum.p = 0.05,
alpha = 0.05)

Finding consensus models across samples...

Generating consensus clonal evolution trees across samples...
Error in aggregate.data.frame(mf[1L], mf[-1L], FUN = FUN, ...) :
no rows to aggregate

Here is the input data file of infer.clonal.models, where vaf.col.names=c("M1.vaf" ,"M2.vaf" "P.vaf"), ccf.col.names=c("M1.ccf" ,"M2.ccf" "P.ccf"), sample.groups=c("M","M","P"), names of sample.groups=c("M1","M2","P").
P is primary tumor, both M1 and M2 are metastasis tumor. P and M are from the same patient.

Thank you very much!

When I add sample.names = samples, where samples=c("M1", "M2", "P"), infer.clonal.models turned to be right, no error occurred.

Thank you!
