Attribute error in apply_genericlist_pars

[aleaf]

Hi, I am getting this error (below) when trying to call apply_genericlist_pars in helpers.py with the following dataframe:

	org_file	model_file	use_cols	index_cols	fmt	sep	head_rows	upper_bound	lower_bound	operator	zone_file	mlt_file	zero_based
51	org/riv_000.dat	external/riv_000.dat	[4]	[6]	free		1	[1e+30]	[-1e+30]	m	nan	mult/rivcond-mult-constant_inst0_grid.csv	False

I am running the latest commit on the develop branch. The error is in this block of code.

assert len(common_idx) == mlt.chkpar, (
    "Probable miss-alignment in tpl indices and original file:\n"
    f"mult idx[:10] : {mlts.index.sort_values().tolist()[:10]}\n"
    f"org file idx[:10]: {new_df.index.sort_values().to_list()[:10]}\n"
    f"n common: {len(common_idx)}, n cols: {len(mlt_cols)}, "
    f"expected: {mlt.chkpar}."
)

Can't figure out where chkpar is supposed to come from, or what it may have gotten replaced by. Thanks for taking a look!

Hey Andy. We added that chkpar recently to make sure the expected number of files is being processed. So I'm wondering if you have updated pyemu but not rerun your pstfrom script? Maybe?

doh! That was it. Thanks for the tip.
