Hi, David In 2.15 there were some changes to the FCS file reading routine to make it compliant with the FCS file standards (it was not compliant prior to 2.15, and led to other errors). Unforunately, the result was that FCS reading was broken (inadvertently) for files from instruments where the manufacturers were not following the standard (apparently there are a lot of manufacturers that don't bother to implement the standard correctly). We're working on correcting these errors as we get bug reports. That said, it's next to impossible to help you out if you don't provide us with some more information.. i.e. provide a reproducible example, sessioninfo(), the error message produced, and even an example of an FCS file where read.FCS fails. We want to fix these issues for users, and we understand that having software suddenly break when it was fine one version ago can be frustrating, but complaining into thin air is not really productive for anyone.

Hi David, is the problem related to empty keyword values as reported by Kieran on 06/13/2012 12:41 PM (i.e., do you see an error like "Error in fcs_text_parse(txt) : ERROR! no end found")? Mike (Jiang), are you considering "fixing" it (e.g., as I suggested on Mon, 18 Jun 2012 15:00:57)? I mean, I know it's not your fault that these instrument vendors are breaking the standard by allowing empty keyword values. However, at the end, it will be flowCore users who will be harmed by not being able to read those files. Ultimately, they are more likely to turn their back at flowCore and stop using it rather than being able to convince instrument vendors to fix their software.

Kieran, Since it's a bug fix it should get pushed to the main page in the next day or two.

Just to follow up on this, I tried flowCore 1.22.3 today, and it worked perfectly. Thank-you for the timeous bugfix.
