Working with 3000 spectra may be challenging with Ifeffit version 1.2, as the total amount of available memory is limited, but with some care it should be possible.
The trick to using Ifeffit 1.2 with a large data volume is to be very careful to reuse the same Ifeffit group name so that array space gets overwritten when importing the next data file. If you keep generating new group names, you will run out of available memory long before getting to the 3000th scan. This limits the amount of data you can look at at one time. It is almost certainly impossible to make a plot of all 3000 spectra at once with Ifeffit, but it is quite possible to process the data sequentially with Ifeffit and then write the data to a format that some other, more capable plotting program can handle.
