Hi @abhay03
Fasta files start with a > on the title line for each sequence. These data do not have quality scores (what most of the FastQC modules profile with statistics). Datatypes - Galaxy Community Hub
The tool Fasta Statistics can generate statistics and do some basic QA.
The FAQs here might help → datatypes. That entire page can be browser searched with keywords like datatypes. You can also search this forum.
This quote from one of those FAQs describes one way to convert fasta to fastqsanger:
If your data is FASTA, but you want to use tools that require FASTQ input, then use the tool Combine FASTA and QUAL. This tool will create “placeholder” quality scores that fit your data. On the output, click on the pencil icon galaxy-pencil to reach the Edit Attributes form. In the center panel, click on the “Datatype” tab, enter the datatype
fastqsanger, and save.
Whether any of that is needed depends on the content of the original data, what your analysis goals are, and the tool(s) that are rejecting the fasta as a valid input. FastQC results would not be very meaningful for a fasta file converted to fastq except to generate a few basic statistics that don’t involve quality scores.
And, this recent Q&A is how to check what datatypes a tool is expecting as valid input: fastq unavailable -- Tool does not recognize inputs? How to check why - #2 by jennaj
