Re: Why Bio::DB::EUtilities->new( -eutil => $eutil, -email => '[email protected]') with no extra argument only works for egquery?

Actually, if you read the error message it does work but you will need to grab the raw output using the get_Response() method.  However, if you are using it this way you will run into problems, primarily b/c each eutil has different required/optional parameters.

If you installed Bio-EUtilities from CPAN there is a script called ‘bp_einfo’ that you can use (it’s a simple wrapper around einfo), which will list the databases and other tidbits of information as needed:

bp_einfo -e [email protected]

protein
nuccore
nucleotide
nucgss
nucest
structure
genome
assembly
bioproject
biosample
blastdbinfo

epigenomics

gds
geoprofiles
homologene

orgtrack
pmc
popset
probe
proteinclusters
pcassay
biosystems
pccompound
pcsubstance
pubmedhealth
seqannot
snp
sra
taxonomy

toolkitall
toolkitbook
unigene
