"blank" in single sample

[GBSB12]

Hi Kathleen, first of all I want to thank you for the great work. My trouble is that I would like to plot a single curve fit but it returns me zero for all values when I try to do a bg correction using blank:

model1 <- SummarizeGrowth(d$time, d$B1, bg_correct="blank") plot(model1)

model1$vals k k_se k_p n0 n0_se n0_p 0 0 0e+00 0 0 0e+00

r r_se r_p sigma df t_mid 0 0 0e+00 0 0 0

t_gen auc_l auc_e 0 0 0

I am new to this stuff and I was wondering if this is something intrinsic to the character of the model which I am not aware of, or I simply overlooked something or if this a bug.
