Error with sequence_tolerance.R processing the checkpoint files, *.ga.entities and *.ga.generations.

Hello,

the output files, *.ga.entities and *.ga.generations, were produced by sequence_tolerance application. 

When I tried to use sequence_tolerance.R processing the output files, I got the following error:

> source("/usr/local/rosetta_src_2021.16.61629_bundle/main/tools/analysis/apps/sequence_tolerance.R")

> process_seqtol("./2I0L_A_C_V2006_0001.ga.entities")

Error in entitieslist[[1]]: subscript out of bounds
Traceback:

1. process_seqtol("./2I0L_A_C_V2006_0001.ga.entities")
2. entities_list_pwms(entities, fitness_coef, temp_or_thresh, type)
3. entities_pwms(entities, temp_or_thresh, fitness_coef, type)
4. levels(entitieslist[[1]][, 1])

May I know the solution of this problem?

Thanks, 

Xiao
