no engine for file type

[Former user]

Hi, the software looks amazing!

However, the writing of the output from the hunt LPP does give the following error:

Traceback (most recent call last): File "LibLPPtiger\LPPtiger_Main.py", line 685, in b_run_hunter File "LibHunter\Hunter_Core.py", line 448, in huntlipids File "site-packages\pandas\core\frame.py", line 1453, in to_excel File "site-packages\pandas\io\excel.py", line 666, in new ValueError: No engine for filetype: ''

Of course, I do have excel installed (office 2016). The other outfiles are there and they contain the expected content.

Many Thanks

Constanze

Dear Constanze,

‌

Thank you for using LPPtiger and reporting issues to us!

It looks like that you are using the source code version of LPPtiger.

‌

Please check if you have following 3 packages installed:

openpyxl
xlrd
xlwt

LPPtiger used these 3 packages to generate excel output.

Please also make sure that on the interface you have the output file created from GUI with “path/file_name.xlsx“

Without .xlsx in the end, the software will not be able to generate the output.

‌

Hope this may help you to solve the problem.

‌

If it is still not working, please download the recent patched exe version and try the demo dataset, and then write us if you can generate the excel output or not.

You can find these files at

‌

Best,

‌

unzip this file and overwrite the obo folder under your LPPtiger folder.

Or you can download this patched version of LPPtiger and delete your previous version of LPPtiger:
