Bootstrapping Issue with Resolution cr-like-em in USA Mode

[caitlinottaway]

I am currently attempting to run alevin-fry to quantify some snRNA-seq data in USA mode with bootstraps. From my understanding, USA-mode should be allowed to be done with bootstrapping, as the bootstrap flag is meaningful with the cr-like-em quantification method, and that method uses USA mode (https://alevin-fry.readthedocs.io/en/latest/quant.html).

However, when I am trying to run this below script, i get the following error. I would appreciate any guidance and clarification!

  alevin-fry quant \
  -t 6 \
  -i $a/alevin_fry/alevinfry_unfiltered_pl_gencode_quants_noforcecells/${c}quant \
  -o $a/alevin_fry/alevinfry_unfiltered_pl_gencode_quants_res_noforcecells/${c}quant \
  --tg-map $a/alevin_fry/salmon_index_files/transcriptome_splici_fl_gencode85/transcriptome_splici_fl85_t2g_3col.tsv \
  -b 30 \
  --resolution cr-like-em \
