When I run the software, it returns an error.
you can see it in the attachment, please give me some suggestion.
thank you very much.

As the error states, "Sequence must start with @: >@ ..." Meaning that Picard is trying to read the sequence and is failing. It calls the method FastqToSam but the file you gave it is in fasta format. You need to convert it beforehand (remove the '>' at the beginning of lines) -
I open and detect my data file, But i don't find ">".
This is a sequence in my data file.

If I run Estimatelibrarycomplexity.jar, it seems that the data format is wrong again.

Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM -
Researchers using sequencing and genomics tools often have to make trade-offs. They can choose between speed or scale, short reads or long-range information, or targeted panels or a view of the whole transcriptome. New technologies that have been released this year are built to address those tough choices.
We asked six companies the same four questions to learn about their latest products. The new technologies bring a lot to the table, including rethinking sequencing...
