[Ifeffit] Sudden Difficulty with Importing Data into Athena

["Dr. Dariusz A. Zając"]

check the data, if at the end of  files are some zeros or strange 
numbers or even empty line(maybe). That what you described can be 
exactly caused by problem with the data in file, eg. injection during 
measurements
