Error in 1:ncol(data) : argument of length 0

I am going to use pulsar to learn a model with pcap file. I have a test2.pcap in the dir of pulsar and when I am going to python pulsar.py -l -p test2.pcap
The below exception raised:

source("prisma.R")
source("dimensionEstimation.R")
source("matrixFactorization.R")
setwd(initial_dir)

load the dataset
data = loadPrismaData(capture_dir)
data = loadPrismaData(capture_dir, skipFeatureCorrelation=TRUE)

And the test pcap are here.

Are intermediate files created? There seem to be a problem with the prisma module.

Some intermediate files were creared. I tried to use different pcap files and seemed to solve it. (I guess there may not be enough information in the previous file.)
