unfortunately, even opj2dat failed to convert the file, although it's only a tiny 2D list

@SjoerdC.deVries: I understand, thank you for clarifying this to me. It would be nice if this could be stressed in the Documentation.

@SjoerdC.deVries: Did you read the other posts? What is then, in your opinion, the mistake? I mean, it's clear that the behavior is inconsistent. But since I'm not the designer of the called function I have no clue what is going on there.

the behavior of ReplaceAll is inconsistent or at least confusing

Is is difficult to add a reverse procedure?

aah, now I understand, I thought it's necessary to have it in FullForm before replacement, thank you!

comment Applying ReplaceAll to I (imaginary unit)
Of course, I understand. However, if I precede in my calculation I have a mixture of "normal form" expressions and FullForm and this generates problems when evaluating scalar products like FullForm[{1, 2, 3}].{1, 2, 3}

@MichaelE2: Both replacements have the same form so I thought: Since it works for x it has to work for "I" too. As I understand Bill, the issue is solved with FullForm[]. However, I thought that InputForm[] will reverse the latter after the replacement. This seems not the case, still searching for the solution...

Thank you! Can you tell me how to revert FullForm[] afterwards?

@MichaelE2: I get the proper transformation from Exp[]-> E^ BUT Exp[-a I] /. I -> -I E^(-I a) however: Exp[-a x] /. x -> -x E^(x a) is evaluated correctly

@MichaelE2: Well, seems strange but this is what I get as output.
