Error when structboundaries = FALSE in gliph2 function

[CharlineJnnt]

Hi, I have encountered an issue when I try to set the parameter structboundaries =FALSE in the gliph2 function. The error was:

> res_turbogliph <- turboGliph::gliph2(cdr3_sequences = data,
                                     n_cores = 1,
                                     refdb_beta = refdb_beta_data,
                                     v_usage_freq = v_usage_freq_data,
                                     cdr3_length_freq = cdr3_length_freq_data,
                                     result_folder = paste0(directory, "GLIPH2/alpha_beta_bis/"), 
                                     lcminove = 10, 
                                     global_vgene = TRUE, 
                                     lcminp = 0.001,

                                     motif_distance_cutoff = 3,
                                     structboundaries = F)

  argument must be coercible to non-negative integer
In addition: Warning message:

  no non-missing arguments to max; returning -Inf

Can you explain the origin of this error ?

I have another question, I've noticed that the default parameters of the gliph2 function are not the same as the original algorithm, so, what are the exact parameters I need to change to get the same result as the GLIPH2 executable?

Thank you for your help !
