• The number of reads generated in your experiment

Once you have entered this information, the calculator will provide you with a coverage estimate for your experiment. This estimate will tell you how many times each base in the genome has been sequenced, on average.

Why is it important?

The coverage depth of your experiment is an important parameter to consider, as it can affect the quality and accuracy of your sequencing results. A higher coverage depth can help overcome errors in sequencing and improve the accuracy of called variants. On the other hand, a lower coverage depth may result in missed variants and reduce the overall quality of your results.

Using the Sequencing Coverage Calculator

Now that we understand what the Sequencing Coverage Calculator is and why it is important, let's take a look at how to use it.

Step 1: Enter the genome size

The first step is to enter the size of the genome you are sequencing. This can usually be found in the reference database or literature for your organism of interest.

The next step is to enter the read length of your sequencer. This refers to the length of the DNA fragment that is sequenced by the machine.

Step 3: Enter the number of reads generated

Finally, you will need to enter the number of reads generated in your experiment. This can be found in the output file of your sequencer.

Step 4: View the coverage estimate

Once you have entered all the required information, the calculator will provide you with an estimate of the coverage depth of your experiment in the form of a graph and table.

Interpreting the Results

Now that you have obtained your coverage estimate, it is important to know how to interpret the results.

What is a good coverage depth?

The ideal coverage depth will depend on the type of experiment you are performing. For most applications, a coverage depth of at least 30x is recommended, as this provides high-quality results while minimizing sequencing errors and missing variants.

What should I do if my coverage is too low?

If your coverage depth is lower than the recommended threshold, there are several options to consider:

• Increase the number of reads generated in the experiment
• Use a longer read length if possible
