What if blast reports an error?
This article will explain in detail how to report errors in blast. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.
When you first learn to use blast according to the official website tutorial (https://www.ncbi.nlm.nih.gov/books/NBK279680/), you will often encounter program errors, such as:
Copy and paste the code directly from the official website and execute:
Makeblastdb-in mydb.fsa-dbtype nucl-parse_seqids
There will always be the following error message:
USAGE makeblastdb [- h] [- help] [- in input_file] [- input_type type]-dbtype molecule_type [- title database_title] [- parse_seqids] [- hash_index] [- mask_data mask_data_files] [- mask_id mask_algo_ids] [- mask_desc mask_algo_descriptions] [- gi_mask] [- gi_mask_name gi_based_mask_names] [- Out database_name] [- max_file_sz number_of_bytes] [- logfile File_Name] [- taxid TaxID] [- taxid_map TaxIDMapFile] [- version] DESCRIPTION Application to create BLAST databases Version 2.4.0+Use'- help' to print detailed descriptions of command line arguments====Error: Too many positional arguments (1), the offending value:-inError: (CArgException::eSynopsis) Too many positional arguments (1), the offending value:-in
Many attempts were made to modify it, and the result was the same. No error was reported until a command was entered manually. After careful comparison, it is found that there is a slight difference in the small horizontal bar in front of the parameter names of the official website command and the manual input command (official website: -, manual input: -). Therefore, you only need to modify the crossbar.
Therefore, you cannot paste the command on the official website directly. You need to manually modify the small bar in front of the parameter name of the command.
