ValueError: Found array with 0 sample(s) (shape=(0, 5000)) while a minimum of 1 is required by MinMaxScaler

Hello, I'm glad to learn this excellent paper. There is a problem with the running of this paper, which takes up your time. I hope to get your reply. After pip install scTAPE1.1.1, I continued to attempt to calculate the error of cell-type-specific gene expression profile (GEP) using a single sample. The error message was as follows:

Sigm, Pred = Deconvolution(simulated_data, '/picb/neurosys/chenrenrui/TAPE/GSE190939/GSE190939_AL_6mo_00.txt',sep='\t',
                           datatype='counts', genelenfile='./GeneLength_mouse.txt',
                           mode='overall', adaptive=True,
                           save_model_name = None)

Are you sure that the data contain samples? I test it on the example data and it works. Please make sure the format is consistent with example data.

Are you sure that the data contain samples? I test it on the example data and it works. Please make sure the format is consistent with example data. Hello! Thanks for your prompt reply. I checked the data and software again, and tried both GPU and CPU versions of the software, and found my problems as follows:

1. Using sample data, it can run normally.
2. I wanted to try a single sample calculation, so I changed the 'kidney_test.txt' in the sample data to keep only one line so that the program would report an error.
3. So if I only have a sample of RNA-seq, how should I proceed with the calculation? I am looking forward to your reply, which will be greatly appreciated.
