getting an unexpected keyword argument error in seqspec init

[bdoughty]

I am trying to follow the tutorial here (https://github.com/pachterlab/seqspec/blob/main/docs/TUTORIAL.md) and am running into an issue. I have installed seqspec via pip (seqspec 0.2.0) and and running the command exactly from the tutorial seqspec init -n SPLiTSeq -m 1 -o spec.yaml "((P5:29,Spacer:8,Read_1_primer:33,cDNA:1098,RT_primer:15,Round_1_BC:8,linker_1:30,Round_2_BC:8,Linker_2:30,Round_3_BC:8,UMI:10,Read_2_primer:22,Round_4_BC:6,P7:24)rna)". I am getting the error: Traceback (most recent call last): File "/oak/stanford/groups/wjg/bgrd/bin/miniconda3/envs/IGVF_utils/bin/seqspec", line 8, in <module> sys.exit(main()) File "/oak/stanford/groups/wjg/bgrd/bin/miniconda3/envs/IGVF_utils/lib/python3.8/site-packages/seqspec/main.py", line 82, in main COMMAND_TO_FUNCTION[sys.argv[1]](parser, args) File "/oak/stanford/groups/wjg/bgrd/bin/miniconda3/envs/IGVF_utils/lib/python3.8/site-packages/seqspec/seqspec_init.py", line 53, in validate_init_args spec = run_init(name, tree[0].descendants) File "/oak/stanford/groups/wjg/bgrd/bin/miniconda3/envs/IGVF_utils/lib/python3.8/site-packages/seqspec/seqspec_init.py", line 70, in run_init assay = Assay( TypeError: __init__() got an unexpected keyword argument 'assay'

Can you try installing from devel?

pip install git+https://github.com/pachterlab/seqspec@devel
