Hi,
as written at https://github.com/BIONF/fDOG/wiki/FAQ#can-fdog-work-with-non-ncbi-taxa, the core compilation step of fDOG cannot work with non-ncbi taxa. I suppose that you have your new species with the ID 39525383 in the blast databases folder (named coreTaxa_dir by default).
Best,
Vinh
P.S.: I see that you open multiple issues to ask about the problems regarding only to the usage of fDOG, i.e. they have always the same topic. It would be more convenient for us if you just post them in one ONE issue entry. Many thanks!

Hi,
There was a strick option in an earlier version of Hamstr. I wonder if there is an option in fDOG that has similar functionality to strick.Or in other words how to make the software run more accurately.

The -strict option is not available anymore in fDOG. I would suggest to choose from the core taxa the reference species as the most closely related species to your search taxa.

Sorry to bother you again, but the choice for the --evalHmmer parameter should be 0.00005 or 1e-6

you must use the decimal format (e.g. 0.00005 for 5e-5)

Hi @majssssa ,
just another info, we found that fDOG performed with a high specificity. The -strict option will just reduce the sensitivity, which is not necessary. You will find this benchmark in the fDOG manuscript, which will be soon published.

HI,
When running fDOG, I added the --rbh option instead of the --rsp option. I found that only one gene was selected for each species. Is this because the conditions are more stringent after adding --rbh, so only one gene meets the criteria, or does the --rbh option select only the most perfect candidate based on the output?

Dear Junpeng,
Thank you very much for your interest in fDOG, and we very much appreciate your feedback!
When it comes to the option „rbh“, please keep the following in mind: rbh is the abbreviation for Reciprocal Best Hit. Since there is always only one ‚best‘ hit, fDOG with this option can return at most 1 ortholog per core-group and species.
From the conversation thus far, I take it that specificity of the ortholog assignment is essential for your analyses. If you want to share some further details about the project in which you use fDOG and the detected orthologs, we might be able to help you in finding the best parameter setting.
Kind regards,
Ingo

Dear Ingo,
Thank you very much for your answer.
My current analysis is mainly about constructing phylogenetic trees with low copy of orthogroup genes to infer phylogenetic relationships of plants, in addition to the complex hybridization and polyploidy events experienced by the plants I study, and many genes have been lost, so I want to get relatively accurate orthogroup, which is important for my later analysis.But if a reference gene only outputs one candidate gene, I don't know how many copies that reference gene has in my species and whether it fits the concept of a low-copy gene.
