My goals are to use a free webtool to:
- Identify guide RNAs (direct-repeat sequence followed by the targeting sequence) appropriate for use with AsCpf1 in order to target a specific segment of genomic DNA.
- Estimate efficiency and specificity of using the guide RNAs identified by the tool.
Unfortunately, when I tried to do this using the CRISPOR tool, the "Job Status" never advanced past the "Waiting" stage, even after 10 minutes. Attached is a screenshot to show what I see.
Specifically, I used the following settings in my query:
I named my sequence:
Mm Acaca block2 from BLAT alignment
In "Step 1" I submitted this sequence:

In "Step 2" I selected:
Mus musculus- Mouse- UCSC Dec. 2011 (GRCm38/mm10)...
In "Step 3" I selected:
TTTN-23bp - Cpf1 Acidaminococcus / Lachnospiracea
My questions are as follows:
- Should I do anything differently to use the CRISPOR tool for my goals?
- Are there other free webtools available for me to achieve the goals I outlined above?
UPDATE: I emailed the folks at CRISPOR, and they informed me the site had been down, but they have since restarted it. Hopefully, their restart is sufficient, but I will leave my question up with the hopes that others can point me to more webtools.
