Error while running RF model about phamb

[bhimbbiswa]

Dear Joachim,

Thank you very much for your kind help.

I am sorry that I misunderstood Henry suggestion.
I had only removed the header from the first line and didn't realize that the header would be there for all files in the concatenated file.

So, I used the following command as you suggested and started my RF model run with the new file.

grep -v "pvalue" all.DVF.predictions.txt > all.DVF.predictions.NEW.txt

This time RF model run finished successfully.

Parsing deepvirfinder
Parsing voghmm
Parsing micompletehmm
Loading Model and annotation table
Writing: 260460 bins to file

Thank you very much @enryH and @sklucas for your suggestions.

I solved this problem by concatenating my dvf files using the code below, keeping only the first header:
awk '(NR == 1) || (FNR > 1)' {input.dvf} > {output.dvf}
input.dvf is a list of all the input files and output.dvf is the concatenated file with only a single header.

Hi Bhim

Did you remove all header lines in the all.DVF.predictions.txt file? if you concatenated a bunch of DeepVirFinder files you will still have headers in multiple lines of the file.

Can you try something like this to make sure there are no headers left:
grep -v "pvalue" all.DVF.predictions.txt > all.DVF.predictions.NEW.txt
Then use the all.DVF.predictions.NEW.txt as input instead.

Let me know if it works.

Best,
Joachim

Can you try to delete the first header line? As I read the error the program fail when it tries to convert score to a float value.

float("score") # fails
float(0.4933076500892639) # should work

Best, Henry

Dear Henry,

Thank you very much for your quick reply.

I tried your solution but still got the same error.

Traceback (most recent call last):

As you suggested, I removed the header line of "all.DVF.predictions.txt".
