peaks_to_linear error

[sdws1983]

Hi,

I'm using graph_peak_caller for graph-based ATAC-seq analysis, I followed the tutorial for profiling and all steps worked successfully. But when I finally got the peak file and I'd like to use the peaks_to_linear command to get the linear coordinates of the peak, the following error occurred:

$ graph_peak_caller peaks_to_linear 01_max_paths.intervalcollection index/01_linear_pathv2.interval 01 01_linear_peaks.bed

Any suggestions?
