Transform Applier "Missing Information"

I'm trying to come up to speed on the transform workflow using the online version of Transform Applier and I'm stuck.  I get errors as follows

1. When I "CreateTransformed AAVSO Report" using V-B coefficients generated by TG ver 6.4, (Tbv,Tb_bv, Tv_bv), I get a "missing information error, need Tv_bv and BVcolor".  TA output box contents:

***TA output box:

I had to enter the coefficients manually, the "Load values from ini file" gave me a SQL error and trace.

TA Transform Issue?


Just to clarify one thing, did you copy/load BOTH a B and V report into the input window?

Were you just transforming two filter image reports as opposed to a time series?  Did you try two color transform link?


PS: You might put this question into VPhot forum rather than software?

Thanks for you reply Ken,

Goodness, I should of put this question in VPhot forum... Sorry!

Yes, I have two reports(V,B). I initially had both B and V reports in the input window, but received an SQL error.  I will go back and verify I didn't have a format error somewhere. I have not tried the two color transform link, but will look at this as well.

I will work on this some more tomorrow and then post any remaining questions on the Vphot forum.
